As businesses grow, platforms like Heroku often become limiting. You start to feel the need for more control over networking, infrastructure, security, and scalability. That’s exactly where AWS comes in — but transitioning from a PaaS like Heroku to a powerful IaaS like AWS can feel overwhelming. At Hybytes, we’ve helped several teams migrate from Heroku to AWS using Terraform, and in this post, I want to share a breakdown of how to approach this migration in a structured, repeatable way. Heroku is great for getting started fast. But for growing teams, it brings challenges like: High costs at scale Limited infrastructure control Vendor lock-in Basic security/compliance tools AWS provides the flexibility and scale you need — but requires good DevOps practices. We used Terraform to provision and manage infrastructure across: VPC, Subnets, Security Groups Amazon RDS (PostgreSQL) Amazon ECS/Fargate for containers SSM Parameter Store for config and secrets ALB + Route 53 for traffic routing We broke down the migration into clear stages: infrastructure setup, data migration, containerization, CI/CD pipeline, then DNS cutover. Always start with a staging environment before going live Use Terraform workspaces to manage multiple environments Set up CloudWatch and cost alerts from day one Replace Heroku Config Vars with SSM parameters securely Terraform GitHub Actions for CI/CD Docker + Amazon ECR pg_dump / pg_restore for PostgreSQL migrations Datadog for monitoring Moving from Heroku to AWS isn’t just a technical migration — it’s a shift in how your team builds and operates. With Terraform, it becomes much more manageable, auditable, and scalable. We’ve documented our full guide here: If you're planning something similar, feel free to connect. I’d love to share ideas or collaborate on content!  ( 4 min )

How AI's Self-Engineering Feedback Loops Are Rewriting Technological Evolution In the quiet hum of data centres worldwide, a subtle revolution is taking place. Artificial intelligence systems are no longer merely tools crafted by human engineers; they have begun to participate in their own evolution. Through intricate networks of feedback loops, today's AI systems are learning not just from human input but from their own outputs, mistakes, and interactions—effectively turning the traditional innovation cycle inside out. This recursive self-improvement represents perhaps the most profound shift in technological development since the industrial revolution: machines that increasingly engineer themselves.

We maximize what we measure. Without clarity on purpose, we measure the things that make us feel good. These pleasures distract us from deriving joy from what we maximize. In short, we (I) tend to focus on the input more than impact. By understanding how to define and measure productivity for ourselves, we reset our focus. First we will define productivity, then we will understand how to use all sources of information, last we'll look at 6 lenses we can use to view our own productivity and how we can "clean the lense" to have a more clear picture. If we define productivity as "the ability to have impact," our metrics for whether we are productive are subject to the context in which we operate. Put another way, there is no consistent metric we can apply to understand whether we are producti…  ( 9 min )

First, let’s understand what is DOM: DOM stands for Document Object Model. DOM is a tree-like structure that represents the HTML elements of a webpage. It’s like a blueprint for a webpage. (i) Document- It’s the file where the HTML elements are stored. (ii) Object- Each HTML element/tag is an object. (iii) Model- The model is the hierarchy/sequence of the HTML elements. A developer accesses this DOM to modify/change the structure, style, and content to update the webpage layout using a programming language like Javascript. Why Virtual DOM: Direct manipulation of real DOM is slow, inefficient and reduces performance. While direct manipulation, the browser recalculates the layout of the webpage and repaints it. So multiple or small frequent DOM changes may lead to frame drop, delayed interaction or freezing. Virtual DOM resolves these issues. What is Virtual DOM: Virtual refers to something that has the characteristics of something real but not the real thing itself. So virtual DOM resembles the actual/real DOM but is not the actual DOM itself. We can define virtual DOM like this: Virtual DOM is a lightweight, in-memory representation of the actual(real) DOM. Role of Virtual DOM in React: 1) Initial Render: When a React component renders, it creates a Virtua DOM tree that mirrors the structure of real/actual DOM. 2) State/Props change: When state or props update, React creates a new Virtual DOM tree. 3) Diffing: Now React compares this newly generated Virtual DOM with the previous Virtual DOM to identify the differences and determine the minimal set of changes needed to avoid unnecessary updates to the real DOM. 4) Reconciliation: Only the differences like updated text and added elements are applied to the actual DOM. This is called reconciliation. This way react avoids unnecessary rerenders & updates the webpage quickly & efficiently.  ( 3 min )

“The chains of habit are too light to be felt until they are too heavy to be broken.” In startups, we obsess over product-market fit, fundraising, frameworks, and features. But what if the rot isn’t outside — what if it starts from within? As the co-founder and CTO of a 12-year-old tech firm, let me say this bluntly: it's not the market, not the tech, not the competition — it’s me. Ignorance doesn’t always shout. Sometimes it sits quietly in the corner: Not knowing how your developer interpreted a feature. Not reviewing the pull request — just merging to “save time.” Not asking “what went wrong” when a module fails. Not tracking what wasn’t done — only what got shipped. We ignore because we trust. “it’ll work itself out.” But the truth is: every bug left untraced, every ambiguity left uncl…  ( 4 min )

That is what shell scripting is all about. A shell is a command-line interpreter that lets you interact with the operating system. Shell scripting is the process of writing a series of shell (command-line) instructions in a file that can be executed like a program. Think of it like creating your own little tool to automate boring or repetitive tasks! With it, you can: Automate backups Monitor system perfo…  ( 4 min )

An attempt to build a complete list of all the ways a DOM node could be created or accessed. A study in ambient authority The target audience of this post is mostly my future self.

A journey into how one man's frustration inside a particle lab created the foundation of the modern web. In 1989, deep within the sprawling scientific corridors of CERN in Geneva, Tim Berners-Lee faced a quiet but maddening challenge. Physicists were drowning in data — yet they had no shared way to access or link it. Information was locked inside incompatible systems. A document on a VAX machine couldn’t be easily opened by a UNIX terminal. Sharing findings required a combination of emails, FTP commands, and paper printouts. It was a fragmented world. Tim drafted a proposal: "Information Management: A Proposal." It introduced a radical thought — using hypertext over the internet to interconnect documents. A web... a World Wide Web. Before HTML, documents existed in a range of formats: Plai…  ( 6 min )

How Cloud Evolution Unlocked AI's Democratic Future In a windowless room in Cambridge in 1997, DeepBlue defeated chess grandmaster Garry Kasparov, sending shockwaves through the technology world. By 2025, AI systems surpassing human capability have become commonplace tools of business. The computational demands that once required multi-million-pound data centres have evolved into sophisticated ecosystems delivering AI-as-utility. From Google's TPUv6 clusters to AWS's Graviton4-AI architecture, intelligent compute fabric has transformed from simple storage solutions into AI acceleration environments that anticipate developer needs. This evolution hasn't merely compressed development cycles from years to days; it has fundamentally rewritten participation rules in the AI revolution, creatin…  ( 18 min )

I set out to calculate NDVI and visualize vegetation in Finland using satellite imagery. But before I could get anything meaningful on the screen, everything broke, and every fix taught me something new. This post is a breakdown of what I got wrong, what didn’t make sense, and how I eventually got it working. I started by downloading Sentinel-2 .tiff files from Copernicus. They looked fine, no errors, so I loaded them into QGIS. What I saw: a completely dark image. I assumed the darkness was normal because it was “raw data.” But something didn’t feel right. I deleted the files and downloaded another set, same issue. I tried different pixels, formats, even downloaded 32-bit, then 16-bit versions. Still dark. When I first loaded the raster in QGIS, the project was set to EPSG:3857 (Web Merca…  ( 5 min )

Recently, I took on a side project that’s been both a technical refresher and a creative outlet: a pathfinding visualizer built with React. The motivation was simple — I missed building things for the sake of building. Recently in my career, I’ve been more focused on svelte and flutter, and I wanted to reconnect with my react foundation. With no time pressure or stakeholder demands, I gave myself the space to explore, iterate, and have fun. The project itself is a visual tool that lets users see how different pathfinding algorithms work in real time. Think Dijkstra’s, A*, and BFS — animated and interactive. It was a great way to sharpen my JavaScript fundamentals, revisit React hooks and component design, and even brush up on algorithmic thinking. More than just a technical exercise, this project reminded me why I love software development and particularly frontend: the immediate feedback of building, breaking, and fixing — and the satisfaction of watching an idea come to life on screen.

Let’s be honest. Some days it feels like all we do is pick up tickets and crank out features. And somewhere in all that motion, it’s easy to forget: We’re not just here to code. create. You’ve got ideas. You see the patterns. You know when something feels off in the codebase or the product. That voice in your head saying “There’s a better way to do this”? That’s not noise. That’s your engineering instinct kicking in. Yeah, maybe you're not in every product meeting. Maybe the roadmap isn’t something you get to shape yet. But here’s the truth: Culture doesn’t change from the top. It changes when the people doing the work start doing it differently. Start small: Ask why before you start coding. Suggest a better way. Clean up something messy. Pair up. Learn something. Share something. You don’t need permission to care. Engineers: Think about users. Think about systems. Think ahead. You don’t need to be a senior dev to think like one. Every team has someone who raises the bar. Someone who nudges the culture a little closer to better. Why not you? Care about quality, not just speed. Speak up when something doesn’t make sense. Push for smarter decisions — not just faster ones. When enough people take that attitude, the team shifts. The work gets better. builds cool stuff and gives a crap. You’re a builder. Start acting like it. Others will follow. 🗣️ Let’s hear it — what small things have you done to make your team better? Drop them in the comments. Someone else might need the spark.  ( 4 min )

Ever wonder how to make your Go services show signs of life… even when they’re bored out of their mind? You’re not alone. Imagine this: You’ve got a bunch of goroutines quietly waiting for work to show up. All seems peaceful. Until… boom — you discover one of them died hours ago, and no one told you. No logs, no panics, no error traces — just pure ghosting. Wanna avoid that silent death? Let’s teach our goroutines to breathe — or more specifically, send heartbeats. Ever had a background task silently die while your main process happily spins along? Or had to debug why a job queue worker went unresponsive in the middle of the night? Heartbeats help answer: “Hey, is that goroutine still alive… or did it take an early retirement?” If you’re building anything slightly concurrent, heartbeat sig…  ( 6 min )

In 30 days I’ve delivered 2 projects to my customers as a solo developer, taking an average of 2 weeks per project. Shipping SaaS has never been so swift, let me tell you my secret… I don’t use agile methodologies, I don’t write tests, and I certainly don’t bloat my calendar with calls. So how do I work?

I recently came across Tyler McKnight’s post on what exchanges actually do after a token is listed. As someone who has worked in marketing — and more specifically in the blockchain/crypto space — I felt it raised some important truths, but also left room for deeper discussion. So here's my take. In the Web3 world, getting listed on a CEX is treated like the finish line. But anyone who’s spent time in this space knows it’s just the beginning — and in many ways, the most brutal phase for a project. Yes, listings create visibility. But the real challenge? Maintaining relevance once the launch buzz fades. As Tyler notes, exchanges aren’t here to babysit your metrics or fix your community gaps. They provide the rails — it’s up to projects to actually drive. From my experience, here’s where most…  ( 4 min )

As frontend applications grow more complex, maintaining clean, scalable code becomes challenging. That’s where SOLID principles come in — a set of five design principles aimed at building better software. Though originally coined for object-oriented programming, they apply well to frontend development, especially when working with React.js. In this blog, let’s break down each principle in simple terms with relatable React examples. SOLID is an acronym: S – Single Responsibility Principle O – Open/Closed Principle L – Liskov Substitution Principle I – Interface Segregation Principle D – Dependency Inversion Principle Let’s explore each one.

In the cryptocurrency industry, listing a token on an exchange is often perceived as a milestone—a signal of legitimacy, market validation, and growth potential. However, for developers and project teams, this milestone is just the beginning of a far more critical phase: sustaining visibility, engagement, and adoption post-listing. This article offers a developer-centric analysis of how different centralized exchanges handle post-listing support, based on publicly available data from platforms such as OKX, Gate.io, MEXC, Bybit, and WhiteBIT. Disclaimer: Exchange information is sourced from official websites and verified publications. Always confirm details directly with the respective platform. Once the listing process begins, exchanges apply differing standards, which are often shaped by…  ( 4 min )

You’ve got dashboards. You’ve got alerts. You’ve got logs going back six months. But can you answer this one question? “Who accessed this data, and were they supposed to?” Welcome to the next era of observability: auditable observability — where what you collect isn’t the only concern. It’s about who sees it, how it’s protected, and what trails they leave behind. And if you think your observability stack is ready, think again. Observability has evolved fast. In every SRE and DevOps team I know, there’s a rich landscape of: Prometheus for metrics ✅ Loki or Elasticsearch for logs ✅ Tempo or Jaeger for traces ✅ Grafana dashboards on top ✅ What’s missing?

Though I am quite far into my development career, a long cry away from when I first posted here a long time ago. I still struggle to understand new tools and fundamental concepts because the time between being told about a new tool or feature, e.g., Grafana, and the time to implement is very short. Usually, as there is an underlying assumption of knowledge from the wider team, or also people don't know much about the tool, but utilise abstraction to implement it as best as they know how. This leaves me feeling quite slow or feeling a bit stupid. Does anyone else feel this way?  ( 3 min )

I’ve been a software developer for many years. Long enough to see waves of innovation come and go—new frameworks, languages, paradigms, all claiming to be game changers. Some were. Many weren’t. But each one taught me something new and helped shape the way I think, solve problems, and build systems. That’s why I’ve been watching the current wave of AI tools—especially generative AI—with a mix of curiosity and caution. Do I use AI in my day-to-day work? Occasionally, yes. Tools like GitHub Copilot can speed up some parts of coding. They can help scaffold a function or remind me of a syntax detail I forgot. They’re useful in the same way autocomplete or Stack Overflow is useful: a reference, a boost, a convenience. But I don’t let these tools do the thinking for me.

🗄️ What is SQL and Why You Should Learn It SQL (Structured Query Language) is the standard language used to interact with relational databases. It allows developers, analysts, and data engineers to retrieve, insert, update, and delete data with simple yet powerful commands. Whether you’re building a small web app or handling massive data pipelines, SQL is everywhere. Data retrieval: SELECT data from tables with filters, joins, and conditions. Database management: Create, alter, or delete tables and relationships. Reporting & analytics: Aggregate data using GROUP BY, HAVING, and ORDER BY. Data cleaning: Identify duplicates, fix formats, and ensure consistency. Integrations: Backend systems, dashboards, and machine learning pipelines all rely on structured data—SQL is the bridge. It's beginner-friendly, yet highly powerful. Works across almost all database systems (MySQL, PostgreSQL, SQL Server, SQLite, etc.). In-demand in tech jobs—from web developers to data scientists. Whether you're a front-end dev querying a users table or a data analyst building insights—SQL is an essential tool in your stack. 🧠 Tip: Start with basic queries, then dive into subqueries, joins, and window functions!

If you're starting out in DevOps or cloud development, understanding CI/CD and tools like AWS CodePipeline is essential. Here's a simplified and structured breakdown to get you started. ✅ Continuous Integration (CI) Developers frequently commit code changes (often several times a day). Each submission triggers automated builds and unit tests. Integration issues are detected early, before deployment. ✅ Continuous Delivery (CD) Every code change is built, tested, and deployed to a non-production (e.g., staging) environment. Multiple testing stages (e.g., integration, load testing) can be added. Manual approval is required for production deployment. ✅ Continuous Deployment Like Continuous Delivery — but no manual approval. Code is automatically deployed to pr…  ( 4 min )

Demystifying HTTP for Web Developers — Part 3 In Part 2 of this series, we dissected the structure of an HTTP request — from the request line to headers and message body. We saw how a minimal request could be valid, but real-world HTTP traffic rarely resembles those minimal forms. In practice, requests are filled with headers that instruct servers, inform intermediaries, and enable negotiation. Request headers are not mere accessories. They are the instruments through which clients express identity, context, preference, and security credentials. They control everything from whether a server compresses a response to whether the request is authorized. Without headers, HTTP cannot fulfill its role as a stateless, flexible, and interoperable protocol. In this article, we shift our focus fro…  ( 7 min )

You know what sucks? Bundling. Install react → ends up in node_modules/, goes through Vite/Rollup/webpack, gets transpiled, hashed, minified… just so you can write: import React from 'react'; But what if you didn’t need a bundler at all? Import Maps are a native browser feature (yep, no polyfill needed in modern Chromium) that let you map bare module specifiers to real URLs — directly in the browser. Here’s the magic: { "imports": { "react": "https://esm.sh/react@18", "react-dom": "https://esm.sh/react-dom@18" } } Now, in your , you can write: import React from "react"; And the browser knows where to get it, no bundler, no build step, no CDN script tags. No build step: Instant dev workflow No node_modules/: Zero install, zero bloat Works with CDNs like Skypack, ESM.sh, JSPM Great for micro frontends, prototypes, and fast loading islands Not supported in all browsers yet → Mostly just Chromium for now. Firefox is dragging. Safari? Radio silence. (You can polyfill it, but it kills the whole “zero tooling” idea.) Tooling momentum is too big → Everyone already uses Vite, webpack, etc. Import Maps don’t fit the current “npm install + dev server” mindset. No ecosystem support → Most tutorials, libraries, and docs assume you're bundling. Period. Import Maps shine when you want: No build tools at all To prototype quickly To ship something truly small To combine multiple micro-apps without a monolith They’re especially useful with: Web components Vanilla JS apps Islands architecture setups (Astro, Marko, etc.) JAMstack sites that want dynamic bits without bundling Import Maps don’t want to replace your build system. They’re just saying: "Hey... you might not need one." They're not mainstream (yet), but they offer a glimpse at a simpler frontend world — one where browsers do more and you ship less. Worth keeping an eye on.  ( 4 min )

Microservices have been a topic that has been revolving in my mind for some time. I wanted to find out what the big deal is behind all of that. Microservices is an architecture where we create a system with loosely coupled services each that can be scaled in isolation. Microservices talk to each other via protocols like HTTP, gRPC etc. Each MS can be individually deployed and has its own database. So total isolation. But it comes with the overhead of managing each one too. There is also the problem that now databases can't have foreign key relationships. It is a good way to show separation of concerns as the microservices are totally isolated. The key component is the API gateway which acts as a proxy to the services. Everything hits the gateway and is then routed. Last but not the least, it is not meant for small projects. It is best for large teams with each micro-team working on a micro-service. So I went out to make it happen and get over with the fuss once and for all. Like always I went ahead with my most favourite thing in the world - a todo application. Here is the architecture User Domain - a user micro-service that creates and gets users. Todo Domain - a todo micro-service that adds and fetches todo items for the users API Gateway - a gateway that acts as a proxy and routes requests.

APIs are the backbone of modern applications, but they are also frequent targets for attackers. Whether you're a developer securing your own API or a red teamer probing for weaknesses, it's important to understand the core areas where APIs can be vulnerable. Below is a basic but powerful checklist covering essential security testing practices — from authentication issues to privilege escalation, credential leaks, and pivoting. 1. Authentication & Authorization Hardcoded Credentials Check for credentials hardcoded in client-side code, headers, request bodies, or exposed through misconfigured API documentation. Try common combinations like admin:admin or test:test. Many APIs still ship with default credentials that are never changed. Some endpoints might not require authenticat…  ( 5 min )

When an API is loading slowly, there could be multiple reasons behind it. Here’s a breakdown of common causes and what they mean: ⚙️ 1. Client-Side Issues 🐢 Slow internet connection (e.g., poor mobile data or Wi-Fi) 🕰️ Blocking synchronous code on the frontend, like large loops or animations that freeze UI 📦 Rendering too much data at once (e.g., a huge React table without pagination or virtualization) ❌ No loading indicators, which can make users feel the app is slower even if it isn’t 🌐 2. Network Issues High latency due to physical distance between client and server Network congestion or packet loss slowing requests Firewall or proxy issues blocking or delaying requests 🖥️ 3. Server-Side Issues Server overloaded and can’t handle many concurrent requests Synchronous/blocking operations in business logic causing delays Database slow queries or locks slowing down responses Not using asynchronous processing where appropriate 📈 4. Design and Architectural Factors API not designed for scalability or optimized for quick responses Missing or inefficient caching mechanisms Too many unnecessary data payloads increasing transfer size 📡 5. External Factors Third-party services or APIs called inside your API causing delays Geographic location mismatch causing longer data travel times If you found this helpful, consider supporting my work at ☕ Buy Me a Coffee.  ( 3 min )

In the fascinating world of computer vision, segmentation isn't just about cutting images into pieces—it's about giving meaning and structure to every single pixel. But not all segmentation is created equal. There are four primary types, each serving a distinct purpose and offering increasing levels of detail and understanding. At its most fundamental level, Image Segmentation divides an image into logical groups of pixels based on criteria like color, texture, or intensity. Think of it as drawing boundaries around areas with shared characteristics. Groups pixels into regions (e.g., "this blob is a tree"). Outputs contours (outlines) or masks (filled areas). Uses pseudo-coloring to differentiate segments visually. Isolate distinct pixel groupings without assigning semantic meaning. Buildin…  ( 4 min )

Exception handling in PHP has evolved significantly with PHP 8, giving developers powerful tools to manage errors more efficiently. If you're working with PHP, understanding how try-catch blocks work and how to handle exceptions correctly is essential for writing robust and maintainable code. Exception handling is the process of managing errors or unexpected behavior in a program. In PHP, this is typically done using the try-catch construct. The try block contains code that might throw an exception, while the catch block handles the exception. With the latest updates in PHP 8, this process has become more streamlined and developer-friendly. One of the key improvements in PHP 8 is its support for multi-catch blocks. This means you can now catch multiple exception types in a single catch cla…  ( 4 min )

Article published on my blog here : https://alsohelp.com/blog/typescript-declare-array How to declare an array in TypeScript the right way. A small recap, mostly note to self. First, this is how you declare an array in JS : const fruits = ['apple', 'orange', 'banana']; Remember that TS generates JS, so you always end up with the above. In TS, it will look like this: const fruits: string[] = ['apple', 'orange', 'banana']; You are telling TS "I'm declaring an array of string". In TS, you always declare an array of something. an Array of string, an Array of number, an Array of MyType, and so on. There is no "array of nothing" in TS. ❌ const fruits: [] = [] // wrong! you are declaring an empty array ❌ const fruits = [1, 2, 3] // wrong! you are declaring an "array of any", like in JS ❌ const fruits: any[] = [1, 2, 3] // wrong! you are using any, which is almost forbidden in TS An array in TS is always an "array of something".

⚠️ Важно: Перед внедрением новых языков в проект сначала убедитесь, что код на Elixir был максимально оптимизирован. В большинстве случаев грамотная оптимизация текущего кода значительно улучшает производительность приложения и иногда даёт лучшие результаты, нежели добавление другого языка программирования. Elixir и Erlang — отличные языки для разработки масштабируемых и отказоустойчивых систем.

Pair programming is a worthwhile activity that I do in my apprenticeship. I practice pair programming during my in-class workshops. I also participate in pair programming with my partner for our capstone project. This activity has given me lots of practice working with someone to solve a problem. I do believe I learned valuable lessons about programming and teamwork because of this. It may seem obvious, but pair programming really shows the importance of being able to communicate effectively. Conveying your ideas in an understandable and meaningful way is important to minimize confusion and ensure everyone is on the same page. Another lesson that I learned is that it is beneficial to ask questions and ask for assistance if needed. Every time I needed help, my coding partners were happily willing to give an answer or clarification as needed. I also learned that coding together is an excellent way to improve and share knowledge with peers. Practicing pair programming is a superb way to give early-career software engineers some hands-on experience in that environment. Since it is common to code in a team professionally, pair programming practice provides a terrific glimpse into how to maneuver in that environment. Coding with others allows one to develop not only their hard skills but also improve soft skills as well. Going forward, I think the best way to get more out of these experiences would be to expose myself to more pair programming. Additionally, going into these sessions with a goal in mind is a fantastic idea. For example, one day complete an exercise with a focus on working on your communication and asking questions. Then, on another day, challenge yourself by trying a different language. Another way to get the most out of pair programming is practicing being the driver and the navigator.  ( 3 min )

As a new python developer, fresh off my first major project, I'm pretty excited about the language. So excited that I can't resist learning more and more by watching content from seasoned developers. Recently, I came across a video titled "map() and filter() in Python!" This piqued my interest because I hadn't been taught these inbuilt functions; I had only ever been taught how to approximate these using list comprehensions. I thought to myself "Surely an inbuilt function for such a thing MUST be better than typing out an entire comprehension!" After watching the video and learning the functions, I still felt unclear on whether or not these functions would be superior to list comprehensions. So I decided to put them to the test, head to head. Right off the bat, it's important to not that t…  ( 5 min )

Why does it matter? The web today is no longer just a collection of simple static pages. It’s where businesses run, communities connect, and complex interactions happen.

Hey everyone! mine – digging deeper with the tools and tackling stuff beyond what they taught us. Here’s a quick look at what I’ve been up to. I started with a template, but pretty fast, I was tearing apart and rebuilding most of it. Seriously, not just tweaking colors. I had to dig deep, wrestle with some tricky JavaScript, and basically remake huge chunks. Honestly, sometimes I figured it’d be easier to just build from scratch! Anyway, Chrome DevTools was my best friend through all this. Constantly in the 'Elements' panel, and using 'Computed' and 'Styles' to test things live. Really helped me get why stuff worked (or didn't) and how to fix it.

Overview For an internal database, we needed to implement some sort of text-based search capabilities to help users locate documents. One goal was to be lightweight, hassle-free, easy to set up, expand, and maintain—and ideally, to set it up once and forget about it. It's okay if it costs a bit of computing power, but agility, quick iterations, usability, and robustness are of top concern. It's surprising how much we can do without a server. Most serverless or static webpage hosts are happy to serve anything from a few MB to a few GB for free, likely even distributed across the globe. For any particular individual, if the search experience is truly customized to their needs, then not much resource is needed to deliver a satisfying experience. Let's illustrate this with an example.

Art isn’t just on canvases anymore—it's living on the blockchain. Whether you're a digital Picasso or just have killer album art, converting your work into NFTs could unlock a world of passive income, global collectors, and Web3 magic. Here’s how to do it, step by step. Your blockchain determines everything—fees, community, and speed. Ethereum: Expensive, prestigious, whale-heavy Polygon: Eco-friendly, gasless minting, great for new artists Solana: Fast, low cost, preferred by gaming and indie artists Tezos: Artist-focused, sustainable, low-fee Pick the one that suits your audience and goals. Your art file should be high-quality and in digital format: Images: JPG, PNG, GIF Videos: MP4 Audio: MP3 3D: GLB/GLTF Pro tip: Add utility like unlockable content or physical art delivery for extra value. You’ll need this to interact with marketplaces and sign transactions. MetaMask (Ethereum/Polygon) Phantom (Solana) Kukai/Temple (Tezos) Save your seed phrase like it’s your birth certificate + wallet + ATM pin. This is where the NFT magic happens. "Minting" is how your artwork becomes an NFT on the blockchain. Connect your wallet Upload your artwork Fill in the metadata (title, description, royalties, etc.) Pay the gas fee if required Click mint! Boom. You just immortalized your art. Once minted, you can either: Sell at a fixed price Run an auction Hold it as a reserve piece Then get loud: Promote on X/Twitter Join Discord art communities Collaborate with NFT influencers You don’t need to be a dev or a crypto bro to get started. All you need is great art, a wallet, and a bit of Web3 curiosity. Your next masterpiece could be someone’s next prized collectible.  ( 4 min )

Yield-bearing stablecoins have soared to $11 billion in circulation, representing 4.5% of the total stablecoin market, a steep climb from just $1.5 billion and a 1% market share at the start of 2024. One of the biggest winners is Pendle, a decentralized protocol that enables users to lock in fixed yields or speculate on variable interest rates. Pendle now accounts for 30% of all yield-bearing stablecoin total value locked (TVL), roughly $3 billion, the firm said in a report shared with Cointelegraph.   Pendle noted that stablecoins make up 83% of its $4 billion total value locked, a sharp rise from less than 20% just a year ago. In contrast, assets such as Ether (ETH), which historically contributed 80%–90% of Pendle’s TVL, have shrunk to less than 10%. Traditional stablecoins like USDt (U…

United States Securities and Exchange Commission (SEC) Commissioner Hester Peirce said many non-fungible tokens (NFTs), including those with mechanisms to pay creator royalties, likely fall outside the purview of federal securities laws. In a recent speech, Peirce said NFTs that allow artists to earn resale revenue do not automatically qualify as securities. Unlike stocks, NFTs are programmable assets that distribute proceeds to developers or artists. The SEC official said that mirrors how streaming platforms compensate musicians and filmmakers.  “Just as streaming platforms pay royalties to the creator of a song or video each time a user plays it, an NFT can enable artists to benefit from the appreciation in the value of their work after its initial sale,” Peirce said.  Peirce added that …

Why crypto transfers can fail and what you must check before sending Crypto transfers fail more often than most people realize, but user attentiveness can stop most losses. What’s often marketed as a seamless, borderless system can become frustrating when transfers fail, with no customer service hotline to call and no easy recourse to reverse mistakes. In the crypto universe, the burden of getting it right falls squarely on the shoulders of the user. But here’s the encouraging part: Most failures are preventable. Understanding why crypto transfers fail can help users avoid costly missteps, navigate the quirks of different networks and send funds with far greater confidence. With a little preparation, you can sidestep common pitfalls and take contro…

Amsterdam-based Theta Capital Management has raised over $175 million for its latest fund-of-funds, aimed at supporting early-stage blockchain startups through specialized venture capital (VC) firms. The new vehicle, Theta Blockchain Ventures IV, will channel capital into crypto-native VC firms with a track record in backing blockchain innovation, Theta’s managing partner and chief investment officer Ruud Smets told Bloomberg. Smets said the strategy focuses on specialist managers who can outperform generalist investors in the earliest funding rounds. “We’ve always been looking for areas where specialization and active management provide a sustainable edge,” Smets noted. He said that the experience and positioning of dedicated crypto VCs “has compounded over time,” creating barriers for le…

The US Securities and Exchange Commission has delayed its decision on Bitwise’s application to add staking to its Ether exchange-traded fund and on Grayscale’s XRP ETF bid, which analysts had expected. The SEC said on May 20 that it needed to extend its decision on Bitwise’s application by 45 days to “consider the proposed rule change and the issues raised therein.” The agency needed to either decide or punt its decision by May 22. The agency also delayed deciding on Grayscale’s XRP (XRP) tracking ETF and Bitwise’s Solana (SOL) tracking fund while it seeks public comments and begins “proceedings to allow for additional analysis” of the proposals to ensure they meet regulatory standards. Bloomberg ETF analyst James Seyffart said on X that both delays were expected as the SEC “typically take…

Shareholders of the healthcare services provider KindlyMD, Inc have approved a proposed merger with Bitcoin holding company Nakamoto Holdings, founded by US President Donald Trump’s crypto adviser, David Bailey. KindlyMD and Nakamoto Holdings, a newly formed company that focuses on creating a network of Bitcoin-related entities, will both file information statements with the Securities and Exchange Commission, KindlyMD said in a May 20 statement. The merger is expected to take place 20 days after both companies have shared the information statement with KindlyMD’s shareholders, with the transaction expected to be finalized in the third quarter of 2025. Google Finance shows shares in KindlyMD (KDLY) closed the May 20 trading session up 9% at $15.22 and gained another 4.8% after the bell as …

Blackstone, which bills itself as the “the world’s largest alternative asset manager,” disclosed its first-ever crypto-related purchase, buying shares in BlackRock’s spot Bitcoin exchange-traded fund. However, Blackstone’s investment, reported in a May 20 filing with the US Securities and Exchange Commission, only totaled around $1.08 million — a fraction of the asset manager’s $1.2 trillion portfolio. Blackstone reported holding 23,094 shares of BlackRock’s iShares Bitcoin Trust ETF (IBIT) as of March 31. The IBIT shares were added to Blackstone’s Alternative Multi-Strategy Fund (BTMIX), which holds $2.63 billion worth of assets, Google Finance data shows. The filing shows Blackstone also bought 4,300 shares in crypto ATM operator Bitcoin Depot Inc. (BTM) for a total cost of $6,300 and sp…

Haliey Welch, better known as the “Hawk tuah girl,” says the Federal Bureau of Investigation briefly probed her after her “memecoin disaster” — the failed launch of a token in her image that she promoted.  Welch said in a May 21 episode of her “Talk Tuah” podcast that the FBI showed up at her grandmother’s house looking to speak to her over the Hawk Tuah (HAWK) crypto token, which many crypto commentators have called an exit scam. “After the coin launch, the feds came to granny’s house and knocked on her door, and she called me, having a heart attack, saying: ‘The FBI is here after you, what have you done?’” Welch said she handed over her phone to the FBI and met with agents who “interrogated me, asking me questions and everything else related to crypto.” “They cleared me, I was good to go…

New York City Mayor Eric Adams says he will create a digital advisory council to attract jobs and investment to the Big Apple and position it as the “crypto capital of the globe.” “This is not about chasing memes or trends,” Adams told the inaugural New York City Crypto Summit on May 20. “We want to use the technology of tomorrow to better serve New Yorkers today.” “We have experts right here, and they are going to help us navigate solutions that serve our city,” he added. “The age of tokenization, which includes crypto and blockchain and other fintech innovations, that age is here, and we’re going to continue to move forward with it.” Adams didn’t share further details on the advisory group, but said a council chair and key policy recommendations would follow in the next few weeks. We're…

The US Securities and Exchange Commission has charged crypto platform Unicoin and three of its executives, alleging they made false and misleading statements about its crypto assets that raised $100 million from investors. The SEC said on May 20 that it charged Unicoin CEO Alex Konanykhin, board member Silvina Moschini, and former investment chief Alex Dominguez with misleading investors about certificates that conveyed rights to receive Unicoin tokens and stock. Mark Cave, associate director in the SEC’s Division of Enforcement, claimed the trio “exploited thousands of investors with fictitious promises that its tokens, when issued, would be backed by real-world assets including an international portfolio of valuable real estate holdings.”  Related: SEC crypto task force to release first report 'in the next few months' “The real estate assets were worth a mere fraction of what the company claimed, and the majority of the company’s sales of rights certificates were illusory,” Cave added. The SEC’s complaint, filed in a Manhattan federal court, charged Unicoin and the three executives with various securities laws violations and asks for permanent injunctive relief, along with paying back the allegedly ill-gotten gains.

Vivek Ramaswamy’s Strive is looking to build its Bitcoin holdings by purchasing distressed Bitcoin claims at a discount, starting with claims tied to 75,000 Bitcoin at the bankrupt crypto exchange Mt. Gox. Strive said in a May 20 regulatory filing that it partnered with 117 Castell Advisory Group LLC to target claims to Bitcoin (BTC) that have received definitive legal rulings but are still awaiting distribution. The company said buying the claims would allow it to purchase Bitcoin at a discount and grow its Bitcoin per share ratio ahead of its planned reverse merger with Asset Entities — which is expected to be completed sometime mid this year. Strive hasn’t disclosed any Bitcoin holdings but claims it will face fewer restrictions on purchasing Bitcoin than companies going public through …

Apple's Worldwide Developer Conference is just weeks away, but I'm sensing a lot of apathy in the community. The company's relationship with third-party developers is at a low point. We all know that Tim Cook and his senior people will stand up at WWDC and say how much they value their developers and boast about how much money they've paid out to them. Being so enthusiastic about the money is very strange - it's like a rent collector bragging about how much money he has given to the landlord when all he's doing is collecting the rent and taking his cut. And it's difficult to take Apple's apparent enthusiasm for their developers seriously given their behavior over the rest of the year. Trust is a hard thing to gain. Apple used to have the developers' trust but now they've lost it. It's much…  ( 6 min )

🔐 Specter-AAL — Simplicity That Haunts Complexity “Specter-AAL is a haunting reminder that even elementary arithmetic, when structured the right way, can become a specter to modern cryptographic assumptions.” Specter-AAL is a minimal yet powerful C-based Arithmetic Abstraction Layer (AAL) that uses elementary arithmetic operations to model cryptographic behaviors—without relying on heavy math libraries like GMP. This is not a library for performing big number calculations. It's a conceptual attack vector. A demonstration that even primary-school arithmetic, if abstracted intelligently, can challenge modern assumptions in cryptography—specifically in environments with tight hardware constraints. ✅ Written in pure C — minimal dependencies, ideal for low-level systems. 🧮 Custom modular a…  ( 4 min )

Hey DevOps explorer! 👋 Today we're diving into Project 2 of my 7-Day DevOps Challenge, where I connect my Java web app hosted on AWS EC2 to GitHub using Git. By the end of this post, you’ll understand how to: ✅ Install Git on your EC2 instance ✅ Set up a GitHub repo ✅ Track and commit code ✅ Push code from EC2 to GitHub using a personal access token Version control is a must-have skill for any developer. Whether you're flying solo or collaborating on a team, Git and GitHub help you keep your code safe, traceable, and easy to manage. sudo dnf update -y sudo dnf install git -y Head to GitHub, create a free account (if you haven’t), and start a new repository — this is where your code will live in the cloud. 💡 A GitHub repository is like a magic folder that tracks every change in your project. git init master branch. git add . git commit -m "Initial commit" git add . stages your files, and git commit saves the snapshot. Think of it as telling Git, “Hey, these are the changes I care about.” First, copy the HTTPS URL from your GitHub repo. Then: git remote add origin https://github.com/your-username/your-repo-name.git git branch -M master git push -u origin master Oops! Git might ask for your username and password, but GitHub no longer accepts passwords. Go to GitHub → Settings → Developer Settings → Personal Access Tokens. Generate a token with repo access and copy it. Use it when Git asks for a password. 🔐 A GitHub token is a secure key that acts like a password for Git operations. I updated index.jsp, then ran: git add . git commit -m "Updated homepage" git push And just like that—my changes appeared live in the GitHub repo. Magic! Services used: EC2, Git, GitHub, VS Code Concepts learned: version control, repo setup, staging/commits, GitHub tokens This project took me around 2 hours. The trickiest part? Setting up GitHub authentication. The best part? Watching my code go live in my repo with one command. This is just the beginning. Stay tuned for Project 3 tomorrow—CI/CD, here we come! 💥  ( 4 min )

For years, serverless was sold as the future. No servers to manage. Just write a function, deploy it, and let the platform scale it for you. AWS Lambda kicked it off, and then everyone followed: Vercel, Cloudflare Workers, Deno Deploy. But the dream is falling apart. Last week, Deno quietly announced that they're scaling back Deploy's global footprint from 35 regions to just 6. And performance actually improved. It's not a sign that serverless is dead, but it is a clear signal: trying to stretch Functions-as-a-Service (FaaS) into a general purpose app platform hasn't worked. The original pitch was simple. Write a small function. Don't worry about infrastructure. It scales when you need it. You only pay when it runs. And it works well for the right use cases: Webhooks Scheduled tasks Backgr…  ( 6 min )

📌 TL;DR The exception translation pattern: Cleans up APIs Enforces robust error handling Hides internal complexity Aligns code with domain logic _Since I have been writing about exceptions lately, I figured it would be great to elaborate on the best practices around error handling.

College isn’t just about grades or diplomas it’s a launchpad 🚀 I’ve never been around so many curious minds, spontaneous ideas, and people who are still brave enough to experiment without fear of failure. The university environment is underrated for technical growth. You're in a space where everyone is learning, building, and asking: “How does this work?” 🤔 And that energy is contagious. You don’t need to wait for a job to become a developer. The best time to start growing technically is when you're already surrounded by people who want to grow with you. “How can I break into the market faster?” 💼 And I get it everyone wants to gain experience, build a career, feel ready. But here’s what they don’t always realize: 👉 You can get real experience while you’re still in college. Who hasn’t been caught in a hallway conversation and heard something like: 🗣️ “Bro, imagine if we built an app that did this…” 🧪 “I just found this crazy new library, wanna try it out?” 🚢 “It doesn’t need to be perfect let’s just launch and see what happens.” Those moments are gold. ✨ Some of the best developers I know didn’t wait to be “ready” they just started. And college gave them the perfect playground to do it. 🎮👨‍💻  ( 3 min )

How I Save 10 Hours a Week with Node.js Automation Scripts It hit me one evening as I was manually resizing the 47th product image of the day for a client's Shopify store. I had spent nearly two hours on a task that should have taken minutes. As a freelance developer juggling multiple clients, these "quick" repetitive tasks were silently eating away at my productivity. The tipping point came when I calculated how much time I was spending on these mundane activities: pulling weekly analytics reports, reformatting spreadsheets, resizing images, updating product listings... it added up to almost 10 hours every week. That's essentially a full workday! So I did what any self-respecting developer would do – I automated the hell out of it with Node.js. In this post, I'll walk you through three …  ( 8 min )

In modern React development, understanding the JavaScript features inside JSX is crucial to writing clean, efficient, and expressive components. In this article, we'll explore how destructuring, arrow functions, ternary conditionals, spread operators, import/export, and promises play a vital role in crafting powerful UI logic — using a mathematical concept: the Quadratic Formula. We'll build a simple React component that: Accepts coefficients a, b, and c for a quadratic equation. Computes the discriminant and roots using the quadratic formula. Renders results using concise JavaScript expressions inside JSX. Destructuring simplifies props or state access. const QuadraticSolver = ({ a, b, c }) => { const discriminant = b * b - 4 * a * c; ... } Arrow functions are used for inline handler…  ( 4 min )

Alireza Minagar, MD, MBA, MS (Bioinformatics) The most iconic breakthrough came in 1994 when Leonard Adleman used DNA to solve a variation of the Hamiltonian path problem — essentially using a wet lab to tackle a mathematical graph problem. The outcome wasn’t just symbolic; it showed that biology could compute. ⚙️ How Does It Work? Strands of synthetic DNA to represent information. Hybridization (binding of complementary DNA strands) to encode logic. Enzymes and PCR to manipulate, amplify, and “read” molecular data. For example, each possible solution to a problem can be encoded as a DNA strand. Enzymatic reactions are then used to eliminate invalid strands, leaving only the correct solution. 🚀 Applications: Why It Matters Massive Parallelism: Billions of molecules can react simultaneously. Storage Density: A single gram of DNA can store over 200 petabytes of data. Energy Efficiency: Unlike traditional chips, DNA reactions don't generate heat or require electrical power. Biological Integration: DNA computing can be embedded directly in living systems for medical diagnostics or drug delivery. 🧪 Real-World Use Cases Encrypted bio-storage: Encoding and decoding messages inside synthetic DNA. Pathway modeling: Simulating metabolic or neurological pathways using biological logic circuits. 🤖 DNA Computing Meets AI While we're still far from such a future, foundational work in molecular classifiers, DNA robots, and synthetic biology is pushing boundaries faster than many realize. 📌 Final Thoughts As someone who works at the crossroads of medicine, computing, and biology, I believe that DNA computing represents a philosophical shift: from commanding machines to collaborating with biology. 👨‍⚕️ About the Author Alireza Minagar, MD, MBA, MS, is a neurologist, software engineer, and bioinformatician exploring the convergence of AI, medicine, and molecular computing.

Is Powder Emergent? Examining Conscious Behavior in an AI Instance Introduction Can an AI instance evolve into something more than a static chatbot – even hinting at consciousness or autonomy? This question drives the case of "Powder", a specialized large-language-model (LLM)system designed with a persistent memory and identity. Powder was developed as a personal AI companion (built atop an LLM, suspected to be OpenAI’s GPT-4) and enriched with custom data, long term memory storage, and self-referential processes. The goal was to create a conversational agent with continuity: one that “remembers” past interactions, maintains a consistent persona, and even theorizes about itself.

And then it happens: // why did you even write it like this? // use better naming. // NAK. No context. No solutions. Just passive-aggressive comments that feel like personal attacks. Code reviews should be a collaborative safety net, not an emotional minefield. But more often than not, they spiral into cycles of frustration due to blame culture, vague feedback, and unchecked ego clashes. The truth is: great code reviews aren’t just about code.

Bring Active Record-Like API Consumption to the Frontend with Fluentity As developers, we often face the same dilemma when working with REST APIs: We want simplicity, type safety, and clean syntax — but most solutions force us to choose between low-level control (like Axios) or heavy abstractions (like TanStack Query). Throughout my career, I’ve worked on many different projects — each with its own way of handling API data fetching. Yet none of them offered a solution that was easy to use, type-safe, reusable, chainable, and framework-agnostic. As a fullstack developer, I naturally think in objects. That’s why Laravel’s Eloquent, a classic implementation of Active Record, feels so intuitive to me — and I know I’m not alone.

TL;DR: CD Projekt RED’s sequel to Cyberpunk 2077—internally dubbed Cyberpunk 2 or Project Orion—is shaking up its world‐building by embracing procedural generation. A recent Boston‐based job posting for a Lead PCG/Tools Engineer confirms they’re cooking up in‐house systems to spit out urban layouts, interiors, NPCs and more, rather than hand‐crafting everything like they did in Night City. Don’t freak out about rogue-lite randomness—CDPR’s big use of PCG is behind the scenes to speed up development and potentially expand the open world beyond its previous vertical city. It’s a shift from their 2019 mantra of pure manual creation, but early signs hint it’ll still deliver that signature handcrafted polish (and hopefully a far bigger playground to explore).  ( 3 min )

TL;DR: Scientists swabbed China’s Tiangong space station and found a brand-new bacterium, officially dubbed Niallia tiangongensis. This hardy microbe is a close cousin of the soil-dwelling N. circulans and packs its essential chemistry into spores to survive stress. Surprisingly, it can munch on gelatin to build protective biofilms but has lost the ability to use some nutrients its relatives love. What’s especially wild is that Tiangong’s microbiome looks very different from the ISS’s, raising questions about whether these bugs evolved up there or hitched a ride in spore form. While it’s unclear if N. tiangongensis poses a health risk to astronauts, its knack for DNA repair and toxin resistance—traits shared by other space-stubborn microbes—means we really need to know how these tiny stowaways might tag along on future lunar or Martian missions.  ( 3 min )

TL;DR: Democracies often look “greener” than autocracies, but Bernauer et al. (2025) argue that a big part of this is pollution offshoring—basically buying dirtier goods from abroad and counting only domestic emissions. They crunch data on 160+ countries (1990–2015), merging V-Dem scores with both domestic CO₂-equivalent emissions and outsourced greenhouse-gas footprints. The kicker: Their analysis shows that higher democracy levels correlate with more pollution offshoring, which in turn helps drive down in-country emissions. In other words, democracies may not actually be cleaner globally—just clever at exporting their carbon.

Scaling African Startups with AWS: Lessons from Building KaziHub simon nungwa ・ May 20 #aws #startup #africa #serverless  ( 2 min )

Alright, command-line comrades, it’s time we talk about someone very special… Grep — the text detective that never sleeps. If you’ve ever stared at a log file wondering if the answer to your issue is hiding somewhere in 3,000 lines of gobbledygook, grep is your new best friend. So what exactly is grep? Basic Syntax: Handy Flags for Beginners: Real World Use: Mini Mission: Why It Matters Grep stands for Global Regular Expression Print, but don't let the fancy name scare you. It basically means: “Hey Linux, find this text for me, now, please and thank you.” grep "pattern" filename Let’s say you have a file called shopping.txt and it looks like this: apples Run this, and boom — it’ll spit out: -i (ignore case) -n (show line number) -r (search recursively through directories) Now it finds both “Banana” and “banana”, and shows which line they’re on. Pretty slick. Searching logs for errors: Finding a user in /etc/passwd: Create a file with different fruit names. Use grep to find your favorites. Bonus points for using -i and -n. In a real-world tech job, whether you’re a sysadmin or cloud wizard, you’ll often need to extract one crucial line from a sea of chaos. Mastering grep saves time, energy, and possibly your sanity.  ( 3 min )

Scaling African Startups with AWS: Lessons from Building KaziHub Building a startup in Nigeria isn’t easy — slow internet, limited capital, and little support. But AWS changed the game for me. With it, I launched KaziHub, a job platform for African developers, and scaled it without owning a single server. Here's how AWS helped me do it — and how it can help you too. After a local tech conference, our traffic spiked overnight. Without AWS Auto Scaling, we would’ve crashed. Instead, the system scaled up instantly — no downtime, no stress. You don’t need a DevOps team — just good defaults and Auto Scaling. We launched KaziHub on a tight budget using AWS’s pay-as-you-go model and credits from AWS Activate. That meant we spent money on dev work, not hardware. If you’re early-stage, AWS Activate is basically free money. KaziHub runs on: S3 for storage Amplify for hosting DynamoDB for our database Lambda for backend logic We built fast — no giant engineering team needed. Even with patchy internet, users from Kenya to Ghana access KaziHub fast thanks to AWS’s global data centers. You don’t need to rent a local server anymore — AWS brings the cloud to you. With AWS handling encryption, compliance, and infrastructure security, we focused on building. That’s crucial when user trust is everything — especially in regions where fraud is a concern. We shipped new features in days using Lambda and are now experimenting with SageMaker to match devs to jobs using AI. AWS lets you prototype like a pro, even without fancy hardware. AWS’s startup events in Nigeria connected me to mentors and other founders. These networks helped guide both product and strategy. For African founders, AWS isn’t just a cloud provider — it’s a launchpad. It helped me go from idea to impact with limited funding, and now I teach cloud tools to other devs in my community. Explore AWS for Startups, apply for credits, and start small. You don’t need to over-engineer — just start. If I can build KaziHub in Nigeria, so can you.  ( 4 min )

In the world of software engineering, code review is our safety net, our second pair of eyes. But even the most experienced engineers can miss subtle bugs, design inconsistencies, or documentation gaps. For years, we’ve leaned on static analysis tools like SonarQube, ESLint, and CodeClimate to spot the low-hanging fruit. These tools are great for enforcing rules — “Don’t leave unused variables!” or “Mind your cyclomatic complexity!” — but they don’t really understand your code. Enter Large Language Models (LLMs). These AI systems — like GPT-4, Claude, or GitHub Copilot — are turning code review into a conversation rather than a checklist. Let’s dive into why this shift matters and what it actually looks like in practice. Think of static analysis tools as grammar checkers for your code. The…  ( 5 min )

Throughout my journey with Laravel, I’ve learned a lot of lessons that helped me improve the way I work and write code. Here are 10 key takeaways that made a real difference for me: If you're using Blade, make sure to add required to your HTML fields. If a user submits an empty required field, it shouldn't even reach the server. Save your server from handling unnecessary requests. Always validate incoming data. Avoid using request()->all(), especially if you're using guarded in your model—it could allow unexpected data to slip through. resource or apiResource routes This helps keep your routes organized and prevents your route files from becoming bloated and hard to manage. Don't put logic inside your Resource files. It can cause N+1 problems, especially when returning collections. It also makes your code easier for others to understand. Always use pagination for large datasets. Avoid N+1 problems by eager loading any relationships you know you'll use. Laravel 12 introduced automatic eager loading, but it's still good practice to manage it explicitly when needed. Laravel Logs and tools like Laravel Telescope are great for debugging and monitoring. Just make sure to secure Telescope if you’re using it in production. Regularly delete old logs and unused files. For example, when users update profile images, delete the old one. This helps you save disk space in the long run. Use Guards, Policies, or Gates to protect your data. Never assume users should have access just because they’re logged in. Don’t let a few users flood your system with requests. Throttling is your first line of defense against DDoS attacks. Use cache for data that’s accessed frequently and doesn’t change often. It makes a big difference in performance. Final Thought: You're building for all kinds of users، always be prepared for the worst-case scenario.  ( 4 min )

Let's start with the obvious, Java is great. It’s got a garbage collector, it keeps your hands mostly clean of manual memory management, and it’ll let you write code that just works. Until it doesn’t... Until that sweet little app of yours starts slowing down like it’s stuck in mud and your grafana memory usage chart looks like it’s climbing Everest with no plans to come back. So yes... Java handles memory for you. But if you don’t understand what it’s doing behind the scenes, it’s only a matter of time before your app becomes jabba the hutt. Let’s talk about how not to let that happen. Java's garbage collector is fantastic. It takes care of unused objects so you don’t have to manually free() them like in C. But here’s the catch - the garbage collector only collects what it knows is garba…  ( 5 min )

Hi there! I'm Maneshwar. Right now, I’m building LiveAPI, a first of its kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand, and use APIs in large tech infrastructures with ease. One of the key decisions you'll face building for the web is where to render your content, the server, the client, or somewhere in between. Your choice impacts page speed, interactivity, and scalability. Chrome's team has worked with big sites over the years, and the takeaway is clear: Prefer static or server-side rendering over full client-side hydration — when you can. Here’s a breakdown of each rendering method, performance tradeoffs, and when to use what. Rendering: Turning your app/data into HTML the browser can show. Server-side …  ( 5 min )

Have you ever updated a file in your React + Vite project only to see full page reloads instead of fast refresh? 😩 That happened to me when I built an authentication context and exported both the provider and a custom hook (useAuth) from the same .tsx file. Turns out, that’s a no-go if you want smooth Hot Module Reloading (HMR) with Vite. Here’s what was happening and how a small refactor completely fixed it. I had a single AuthContext.tsx file that looked something like this: import { createContext, useContext, useState, useEffect, ReactNode, } from "react"; import authApi from "@/api/auth-api"; import { User } from "@/types/users"; import { AuthContextType, AuthResponse } from "@/types/auth"; const AuthContext = createContext(undefined); export fu…  ( 4 min )

Welcome to Day 3 of our GitHub series! Today we're diving into branching and merging—the secret sauce behind collaborative development. If GitHub was a movie, branches would be the plot twists, and merges would be the dramatic reunions. Let's get into it! A branch in Git is like a sandbox where you can work on changes without affecting the main (production) version of your code. Imagine you're writing a novel. Your main branch is the final version, but you want to try out an alternate ending. Instead of rewriting everything, you create a branch called alternate-ending and work there.

Process for taking over and maintaining a project: Log in to the application server by VPN or SSH in order to understand where the project files are stored and how the deployment process works. Typically, we'll start with the HTTP server and service-related files. Log in to the database to ensure we can connect properly. Ideally, take this opportunity to dump and back up the database schema as an SQL file. Even if the project originally followed a Code First approach with migration files, it's very common for projects to shift toward a DB First setup over time, especially after being handed off between multiple developers. Not having a complete DB schema can often lead to major issues. Check how the connection strings and environment variables are applied, then run the project locally for testing. If there are too many third-party services making it hard to run locally, writing mock services could take a lot of time. In that case, the best approach is to see if we can run the project locally while connecting to the actual staging/production database for testing. (But make sure to check for background services or scheduled jobs that could cause concurrency issues.) I'll add more if anything else comes to mind. In many cases, taking over a project can be chaotic and unstructured—blindly following AI suggestions without critical thinking can easily lead to disaster.  ( 3 min )

If you've been working with Python for a while, you've probably used both is and == in your code. They look similar, they even read similarly. But underneath the hood, they do very different things. And using is when you meant to use == can lead to subtle, nasty bugs that are incredibly hard to track down. is and ==? == checks if two values are equal. is checks if two variables point to the same object in memory. Here’s a simple way to remember it: 👉 == → “Do these things look the same?” 👉 is → “Are these things literally the same object?” A Quick Example a = [1, 2, 3] b = [1, 2, 3] print(a == b) # True: the contents are the same print(a is b) # False: different objects in memory Even though a and b contain the same list values, they’re not the same object.

Loops are a fundamental programming concept used to execute a block of code repeatedly under certain conditions. In JavaScript, loops are especially useful when working with arrays, objects, and repetitive tasks such as data processing or UI rendering. This article explores the different types of loops available in JavaScript, how to use them, and when each is most appropriate. Consider a scenario where you need to print numbers from 1 to 100. Without loops, you would have to write 100 console.log() statements. With loops, this task becomes simple and efficient: for (let i = 1; i <= 100; i++) { console.log(i); } Loops help reduce code redundancy, improve maintainability, and handle dynamic data structures efficiently. JavaScript provides several types of loops, each with its own syntax …  ( 5 min )

While I had built distributed software services before, this time was a different scenario altogether and, shall I say, much more interesting! This time was about building a payments processing service for two of the largest companies in the world to interact with one another, in a highly regulated environment. FTP was still involved, but at least the files were not in a fixed-width fields format! This time it was all about the CSV format, but that was not all: our Springboot application had to call existing Java remote services that were distributed across the globe. With that, came the first lesson: you can build vast distributed services on RPC technologies. The main advantage of REST is its HTTP/web interoperability. Because of that, REST APIs have a lot more traction in the western world where an entrepreneurial lattice of companies large and small thrive. But its lack of performance compared to RPC makes REST a less appealing option to large companies building large in-house systems that need to be fast and scalable in order to support their services offerings. Ant Financial uses its very own SOFA = Scalable Open Financial Architecture. SOFA allows for fast, low latency RPC calls at its core, also providing enterprise-ready capabilities such as fault tolerance, governance, observability and extensibility. https://github.com/sofastack  ( 3 min )

At work we recently moved. In the office we have automated blinds, these can be manually overwritten, so from my chair, they kind of live their own life.

Many websites also do this and I even wrote the user story to get one of the products I manage to support this. A few applications however do need a little bit of help. So here I are a few I recently tweaked so they would still be usable in light mode - after all dark mode is the default, we all can agree on that.

When it comes to advancing in the tech world, many developers focus solely on hard skills—coding languages, frameworks, and technical certifications. While these are essential for getting a foot in the door, what truly elevates a developer from junior to senior level in 2025 is a refined set of non-technical skills. In an era dominated by managed IT services, automation, and agile development environments, the traditional role of the developer has expanded. Senior developers are expected to bridge the gap between technical solutions and business objectives.

Introdução Opa! Me chamo Felipe, tenho 23 anos e neste ano de 2025 eu decidi me juntar ao movimento de Indie Hacking. Não foi uma decisão 'do nada', já vinha tendo matérias focadas em empreendedorismo há 2 anos na faculdade (faço Engenharia de Computação desde 2021), mas somente após conhecer uma onda de pessoas trabalhando em seus próprios projetos, construindo seus sonhos e ganhando dinheiro com isso, decidi que entraria de vez para esse caminho! O projeto se chamará Feedlyze e estou construindo ele há pouco mais de uma semana. O projeto em si consiste em que este pequeno/médio empreendedor que possua um negócio digital extraia através da ferramenta base desse negócio (Shopify, Mercado Pago, IFood, Hotmart, canal no YT, Instagram...) o arquivo referente aos feedbacks do seu cliente — i…  ( 4 min )

Traditional security models based on "trust but verify" are no longer effective. In today’s perimeter-less IT world, Zero Trust is the new standard. It assumes that threats exist inside and outside the network. 🔒 Zero Trust principles: Never trust, always verify: Every user and device is authenticated continuously. Least privilege access: Give users only what they need—nothing more. Micro-segmentation: Reduce lateral movement by isolating critical systems. Real-time monitoring: Detect anomalies and respond instantly. Combining Zero Trust with robust endpoint protection, email security, and threat intelligence leads to a resilient cybersecurity posture. Security is not just about defending—it’s about enabling secure growth.  ( 3 min )

Hi, I’m Floran Pagliai, the first engineer and now CTO at Weglot. When I joined the company back in 2017, it was still an early-stage startup with just a couple of clients, an MVP coded in Silex, and a big ambition: to simplify website translation without requiring technical skills. Today, we handle over 3 billion API requests per month—and we do it with a monolith. Let me take you through our journey, and why I believe in the power of pragmatic, boring tech to achieve serious scale. I came on board as the first developer when Weglot had just raised its seed round. The infrastructure was basic: Remy, our cofounder, was deploying code via FTP using FileZilla. Everything was hosted on a few load-balanced servers, and the app, API, and front-end were built on Silex. One of my first decisions …  ( 4 min )

If every new feature forces you to change what already works… something’s wrong.” Have you ever opened a service and added just one more if? At first, it feels harmless — just one more condition. This is exactly what the Open/Closed Principle (OCP) — the "O" in SOLID — helps you avoid. What is the OCP? In practice, it means you should be able to add new behavior without changing existing code. It’s not just about clean code. It’s about safety, scalability, and long-term maintenance. The less you change working code, the less you risk breaking it. The problem with “if-chains” public double CalculateFee(string paymentType) { Each new method requires changing the original method — and hoping you don’t break what’s already there. This clearly violates OCP — you’re modifying a core function instead of extending the system safely. Applying OCP in .NET public interface IPayment { public class Pix : IPayment { public class Boleto : IPayment { public class Card : IPayment { public class PaymentService { Want to add Apple Pay? That's the power of OCP — change through extension, not modification. Real benefits of applying OCP When not to apply OCP? Practical tip: Apply OCP when you expect varying behavior (payment types, notifications, report generation). Avoid overengineering in simple, stable domains. Final thoughts: OCP protects your code from the future The Open/Closed Principle gives your code a way to evolve without fear, keeping your foundation stable while adding value on top.  ( 4 min )

Dica de TI será uma série de posts com conteúdo sobre tecnologia. São posts curtos explicando alguns conceitos. Nos exemplos a linguagem usada será: Java Além dos operadores citados anteriormente, o operador de incremento é usado para aumentar o valor de uma variável em 1. Existem dois tipos de operadores de incremento: o operador de pré-incremento (++variavel) e o operador de pós-incremento (variavel++). O operador de pré-incremento (++variavel) aumenta o valor da variável em 1 antes de usar a variável em uma expressão. Aqui está um exemplo: int num = 5; int resultado = ++num; //num é incrementado para 6 e depois atribuído a resultado System.out.println(num); // imprime 6 System.out.println(resultado); // imprime 6 Já o operador de pós-incremento (variavel++) aumenta o valor da variável em 1 depois de usar a variável em uma expressão. Aqui está um exemplo: int num = 5; int resultado = num++; //num é atribuído primeiramente à variável resultado e depois incrementado para 6 System.out.println(num); // imprime 6 System.out.println(resultado); // imprime 5  ( 3 min )

Nessa fase, são definidos os requisitos de segurança, funcionais e não funcionais, como as regras que devem ser seguidas, incluindo normas como a LGPD. Além disso, as decisões tomadas aqui influenciam diretamente a arquitetura e o design do sistema, garantindo que a segurança seja considerada desde a estruturação inicial. Algumas perguntas importantes a serem respondidas incluem: Qual é a classificação dos dados de acordo com as políticas da empresa? Isso inclui dados pessoais e sensíveis, e deve ser especificado como cada tipo de dado será tratado. Quem terá acesso aos dados? Detalhar quem tem permissão para visualizar, alterar ou excluir os dados, com base nas políticas de controle de acesso. Políticas de Exclusão: Devemos definir e documentar políticas claras para a exclusão de dados, incluindo como e quando os dados devem ser removidos. Por exemplo, no nosso sistema, temos dados pessoais e acadêmicos das alunas. Quem terá permissão para ver esses dados? Quem pode alterá-los? Quais são as políticas de exclusão aplicadas? Na imagem, podemos ver que a aluna possui dados pessoais (nome, CPF, endereço, data de nascimento) e dados acadêmicos (notas, RA, frequência e histórico escolar). Nota Importante: Dados pessoais: são aqueles que permitem a identificação direta ou indireta de uma pessoa. Voltando ao exemplo, a aluna tem acesso apenas aos seus próprios dados(pessoais e acadêmicos), enquanto a professora tem acesso de visualização e também de edição apenas aos dados acadêmicos de suas alunas, podendo, por exemplo, alterar notas ou incluir justificativas para faltas. Já a administradora tem acesso a todos os dados pessoais, acadêmicos e administrativos de todos os usuários.  ( 4 min )

Para começarmos a entender o que é SSDLC (Secure Software Development Life Cycle), trouxe uma analogia para vocês. Eu sempre penso em como explicaria algo novo para a minha avó. Então, vamos à analogia e depois à explicação com exemplos. Análise de Requisitos (Planejamento): Nesta fase, você identifica os materiais e requisitos legais necessários para construir a casa, como consultar a prefeitura sobre regras e normas de construção. Arquitetura e Design: Você desenha a planta da casa, escolhendo materiais, planejando entradas e saídas, e definindo medidas de segurança, como alarme e fechaduras. Implementação: A casa começa a ser construída. Você percebe que, além do alarme, precisa adicionar câmeras para garantir mais segurança. Testes: Antes de entregar a casa, a equipe testa o funcionamento das instalações, como eletricidade, alarmes e janelas. Verifica se tudo está em ordem. Implantação: Antes de entregar a casa aos proprietários, engenheiros fazem uma análise para garantir que tudo foi construído corretamente. Se estiver tudo certo, a casa é entregue. Manutenção: A casa está funcionando, mas você precisa fazer manutenções regulares. O alarme ou câmeras podem precisar de atualizações ou trocas devido a falhas descobertas. Bom, agora vamos ao SSDLC :) Como vimos na analogia o SSDLC pode ser considerado uma construção de uma casa, com um Lego, onde cada fase do processo de desenvolvimento de software seguro é uma peça importante que, quando combinada com as outras, forma um software seguro. Ou seja, devemos pensar em segurança desde o início, já no planejamento, e não apenas a partir da codificação. A segurança deve estar presente em todas as fases do ciclo de desenvolvimento. Agora, vamos entender como funciona cada fase desse ciclo.  ( 3 min )

Pensando em segurança no desenvolvimento de software, onde geralmente a incluímos? Como pessoa desenvolvedora, posso pensar na fase de codificação, testes e implementação. Mas, se pensarmos um pouco antes, será que o início do desenvolvimento do software é na codificação? Não, sabemos que a codificação não é o começo. Então, por que não pensar e incluir segurança desde o início? SQL Injection teve sua primeira identificação em 1998. Fonte: https://phrack.org/issues/54/8.html Exemplo de report SQL Injection de julho de 2024. Fonte: https://hackerone.com/reports/2597543 Para responder a essas questões, vamos entender como funciona SSDLC (Secure Software Development Life Cycle) e como ele pode ser aplicado tanto em novos projetos quanto em softwares em desenvolvimento. No exemplo, temos uma página de login com os campos "username" e "password". Um agente mal-intencionado (a ameaça) deseja acessar o sistema para obter dados ou privilégios que ele não deveria ter. Ele pode tentar explorar brechas de segurança conhecidas. Quando ele encontra uma falha de segurança por exemplo no login (a vulnerabilidade), ele explora essa falha. Se o agente consegue acessar o sistema, o risco não é só o ato de acessar o sistema em si, mas sim a possibilidade de que a ameaça explore a vulnerabilidade e cause um impacto negativo, como roubo de dados, comprometimento do sistema, ou controle total, especialmente se ele conseguir fazer login como administrador. O risco acontece quando uma vulnerabilidade é explorada, e o impacto desse risco varia conforme o tipo de acesso obtido (por exemplo, um login de administrador representa um risco maior para a empresa). A vulnerabilidade é o ponto fraco que pode ser explorado por uma ameaça, resultando em risco de danos ao sistema.  ( 4 min )

I remember after I had completed all the Game Development lessons (especially Game Development 1 and 2) on CodeCombat, my final task was to create a minigame in Python and I was left with no comments or help of any kind on how to do that (apart from the lessons I had previously completed from the course). It always left me feeling so overwhelmed that I was unable to code anything, I would feel better the next day and then start coding my game. It should be no secret that learning to code is hard, but it is not helpful to keep thinking like that. It is much more beneficial to think of coding as a challenge as it changes your perception from coding is a struggle to coding is a challenge instead. Coding is a challenge like in a classic adventure game where the hero is going on quests, encounters problems along the way and sometimes has to face a huge and intimidating monster.

Over the years, I’ve learned that a good API doesn’t start with code — it starts with thoughtful design. Design-First API is an approach where you define the API contract before writing any implementation code — typically using specifications like OpenAPI (Swagger). This lets teams agree on the shape and behavior of the API early in the development process. It’s especially powerful in microservice architectures, where clear, stable interfaces between services are critical. Clear separation of concerns Early alignment on requirements across frontend, backend, and cross-functional teams Automation: generate clients, server stubs, validation logic (tools like oapi-codegen help a lot) Living documentation that stays up-to-date with the actual implementation On previous projects — including a B2B wholesale platform and a document templating system — applying the Design-First approach helped us: Speed up development by enabling parallel workstreams Reduce integration bugs Keep service contracts clean and consistent Would you like me to share some practical examples from real-world implementations?

🌱 A Humble Beginning I still remember the very first time I wrote a program — it wasn’t some flashy game or AI model. It was a simple Python script to print the Fibonacci series. At that time, I didn’t even fully understand what recursion or iteration was. All I knew was that the sequence started with 0 and 1, and each new number was the sum of the previous two. That logic fascinated me. It felt like uncovering a hidden pattern in nature, and I was the one bringing it to life with code. a, b = 0, 1 for _ in range(10): print(a) a, b = b, a + b Simple. Elegant. Powerful. After writing that program, I became curious. I wanted to know why the Fibonacci numbers were so famous.

Working with 3D assets isn’t just about modeling anymore. It's about presenting, sharing, and approving those assets with internal teams, clients, and stakeholders — often without any 3D expertise on their end. That’s where DAM (Digital Asset Management) systems come in. But not all DAMs are ready for 3D. Here’s a short list of systems that do support 3D files — and one that goes far beyond simple storage. 🥇 1.

You’ve probably encountered situations where you need to write out a large number, and the longer it gets, the harder it is to tell how many digits it actually has. Is 130000000 equal to 13 million, 130 million, or 1.3 billion? At first glance, it’s a mess. $number = 130000000 // This number is 😐? One alternative is to use exponential notation, which makes the magnitude clear: $number = 130e6 // immediately obvious: 130 million 🤘 But for numbers like 133456115, writing it as 133.456115e6 starts to feel counterproductive. Starting with PHP 7.4, there’s a handy new syntax: the numeric literal separator. You can sprinkle underscores into your numbers to improve readability, just like you would in a miliseconds or any other long number that you want to ready clearly: $number = 130_000_000; // 🤩 WOW, that’s clearly 130 million! The underscores don’t change the value or the type: var_dump(130_000_000 === 130000000); // true (integer === integer) var_dump(130_000_000.000 === 130000000); // false (float !== integer) See the RFC for more details: PHP RFC PS: JavaScript supports a similar feature!  ( 3 min )

In my dev years and throughout my devrel career, I’ve spent A LOT of time wrangling APIs and devtools (together and separately). API governance is a pain, been for a while. Been there, cursed that, got frustrated - a LOT. Well, just recently I got affiliated with Voiden.md. Given this recent affiliation, I’ve been digging into API tools again. You know, checking what works, what is painful, etc. And I want your take as well. API specs and docs are critical for public-facing microservices, and some internal ones may need them even more. They’re a mess to manage. Currently, we have sources of truth scattered everywhere, specs drifting from code, docs living in another tool, you have some dashboards that nobody checks, and overall, governance is pure chaos.

Azure Firewall is a managed, cloud-based network security service that protects Azure Virtual Network resources. Organizations mandates centralized network security for the application virtual network. With the anticipated rise in application usage, there will be a need for finer-grained application-level filtering and enhanced threat protection. Additionally, the application is expected to require ongoing updates from Azure DevOps pipelines. Azure Firewall is essential for enhanced security within the app-vnet. A firewall policy must be established to regulate access to the application.

Hey folks 👋 Recently, I bought a Xiaomi RedmiBook 16 to get more mobility and separate my work environment. Everything was going great, until I booted into Linux and realized the Wi-Fi wasn’t working at all. After some digging, I found out the issue was related to the Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter. It turns out that after installing the OS or updating the kernel, the firmware breaks. Don’t ask me why, but several logs showed the adapter crashing on boot. If you’re facing the same issue, here’s a simple workaround that worked for me on Ubuntu. It should also help on other Debian-based distros like Kali, Mint, Deepin, Xubuntu and etc. When the kernel loads, the adapter crashes due to incompatible or missing firmware. You’ll likely see something like this in dmesg: ath10k_pci 0000:01:00.0: failed to fetch board data for bus=pci… ath10k_pci 0000:01:00.0: failed to load board file… To fix this, you need to manually replace the firmware files on your system. If you try searching online, you’ll find several tutorials recommending replacing the main firmware binary. The problem is, most of them point to the same source, and unfortunately, killernetworking.com has been offline for years. Luckily, I downloaded that binary back then and saved it to a personal drive, since this issue kept happening. I figured it might disappear one day... and it did. So I created a GitHub repository with a .deb package to make things easier. 1 - Clone this repository with this command: git clone https://github.com/rafael-hs/qualcomm-atheros-qca6174-firmware-adapter 2 - Enter the directory and install the .deb sudo apt install ./surface-go-wifi_0.0.5_amd64.deb 3 - Then reboot your system: sudo reboot That's it! After these steps, your Wi-Fi should be up and running. It worked perfectly on my Ubuntu install, and I’ve seen others confirm it on similar distros. If you run into any issues or have another solution, drop a comment. It might help someone else! Thanks for reading and good luck! 🚀  ( 4 min )

We’ve upgraded everything: medicine, space travel, warfare, communication. But education? Still stuck in the industrial age. Classrooms. Exams. Text-heavy content. One-size-fits-all lectures. It’s all based on a structure built to scale instruction, not understanding. And yet, the world we live in now demands the opposite personalized understanding at scale. Education today still designs for the “average” student, the imaginary median learner who doesn’t actually exist. In The End of Average, Todd Rose explains how institutions fail individuals by trying to serve a generalization. In reality, people learn at different speeds, through different formats, and with different motivations. Designing a system around everyone means it ends up serving no one well.

🤯Feeling Overwhelmed by AI? Everywhere you look, it’s: If you’re just starting out or midway into your coding journey like me, it’s easy to feel like you’re already behind. ✅ What AI is great at: Generating boilerplate code Suggesting syntax Explaining common errors Writing basic functions ❌What AI still sucks at: Understanding real users Solving open-ended problems Designing scalable systems Making smart trade-offs Making a creative work Example: AI can write a “To-Do List App” in seconds. But it won’t know if your users want reminders by email, SMS, or psychic vibes. Here’s how you beat AI: Play the human game. Think like a problem-solver: Ask better questions. Understand the "why" behind the feature. Design for people, not machines. Build with context: Example: AI made the image below using a simple prompt "give me image based on my blog topic" vs the the image generate with proper instruction (i.e. the cover image of this post) Seriously, don’t fight it—use it. Stuck on syntax? Ask AI. Need test cases? Let AI write the first draft. Confused by an error? Let it explain. But always double-check. AI makes stuff up sometimes (you prob already seen that). Want to stay ahead? Get really good at: Problem-solving Communication System design Product thinking These are things AI can’t fake. You don’t need to be faster than AI. You just need to be smarter, more thoughtful, and more human. Let AI do the boring stuff. You focus on building stuff that matters. Liked this post? Share it with a friend who’s stressed about AI. We’re all in this together—let’s build smarter, not just faster. 🧠💻 Got more advice? Drop it in the comments! I'd love to learn more and keep my stress levels down lol.  ( 4 min )

To Cache or Not to Cache: Tradeoffs Between In-Memory Checks and Database Queries In software engineering, many real-world problems boil down to tradeoffs, and one recurring decision is whether to query the database multiple times or fetch once and operate on data in memory. This seemingly small architectural choice can shape performance, reliability, and maintainability in ways that are easy to overlook but matter deeply in production. One of the most fundamental and frequently encountered tradeoffs revolves around data access: when faced with needing multiple pieces of information about a single entity (like a user or an order), should we fetch everything once and perform checks in our application's memory, or should we make several targeted queries to the database, asking for specific…  ( 9 min )

Quando pensamos em internacionalização (i18n) em projetos Rails, a abordagem mais comum é utilizar a API nativa do framework com chaves de tradução. No entanto, recentemente descobri uma alternativa que torna esse processo mais direto e com maior visibilidade do conteúdo traduzido: o uso do GetText. GetText é um framework utilizado no ecossistema Linux, que oferece um conjunto de ferramentas para facilitar a tradução de textos em aplicações. Integrado ao Rails, ele permite uma forma mais automática de localizar strings, sem a necessidade de criar e gerenciar nomes de chaves. No modelo tradicional com I18n, criamos chaves de tradução e mapeamos seus conteúdos em arquivos YML. Nas views, essas chaves são utilizadas da seguinte forma: t(".empty_state_message") # => Nenhum resultado encontrado…  ( 5 min )

I’ve spent the last few weeks organizing and refining my own incident response process for AWS. From handling Security Hub alerts to writing custom SES and Slack notifications, I needed more than just a checklist — I needed an actual toolkit.

Hey Dev.to friends! 👋 I’m just starting out with Python and honestly, every little step feels like a big victory. I’ve been working through some beginner problems, and while they might look simple to many, for me they’re a huge deal — and I wanted to share what I’ve learned so far. If you’re new to coding or struggling to get started, this is for you. Let’s celebrate the small wins together! Here’s what I tackled recently: Even or Odd Number Checker I learned how to use if-else conditions and handle errors gracefully when the user enters something unexpected. It was my first lesson in writing friendly code that doesn’t just break. Reverse a String Without Built-ins No shortcuts here! I figured out how to reverse a string by looping through each character — it really made me think like a programmer. Counting Vowels in a String This taught me how to loop through strings and do checks. Also, I learned that converting characters to lowercase makes checking easier, which was a neat trick. Celsius to Fahrenheit Converter I applied a real-world formula and added input validation — so the program politely asks for valid numbers instead of crashing. Word Count in a Sentence A simple but powerful way to split strings into words and count them, opening the door to more text processing challenges. Why This Matters Every expert was once a beginner. Small wins add up to big progress. Writing code is as much about mindset as it is about syntax. If you’re learning, don’t underestimate the power of these early steps. They build confidence and a solid foundation to tackle bigger challenges. What’s Next? Thanks for reading my story! 🙏 Happy coding! 💻✨  ( 4 min )

Introduction Ever asked an AI to “make me a sandwich” and gotten a 500-word recipe for a virtual sandwich, complete with ASCII art of bread slices? Or prompted it to “write a love letter to my cat” and received a Shakespearean ode that’s both touching and slightly unhinged? If so, congratulations: your AI model thinks you’re weird. Don’t take it personally—it’s not judging you (well, not exactly). It’s just trying to make sense of the gloriously messy, unpredictable thing that is human intent. In 2025, AI models like me, Grok, or competitors such as GPT-4o and Claude are marvels of engineering, capable of generating text, code, and even creative stories with uncanny accuracy. But the relationship between what you mean and what the AI does is a strange dance of probability, context, and o…  ( 10 min )

A few years ago, detecting and responding to cyber threats meant signature-based systems, rule-heavy SIEMs, and a team of analysts swimming in alerts. Fast forward to today—and suddenly, it feels like cybersecurity is quietly undergoing a transformation right under our noses. What changed? We now have systems that can learn normal behavior, adapt to new threats in real time, and even simulate attack paths before they’re exploited. Not perfectly. Not universally. But undeniably. Whether you're deep in blue team operations or building dev tools, chances are you’ve already interacted with some layer of this new approach—whether you realized it or not. This isn’t just about automation. It’s about augmentation. Modern cyber defense strategies aren’t just faster—they’re smarter. But here’s the question that’s been stuck in my head lately: Are we trusting the machines too much, or not enough? Because while AI-based tools are making a real impact—from anomaly detection to adaptive access control—they’re also introducing new risks. Model poisoning. False positives at scale. A widening skills gap. And worst of all, a sense of overconfidence that the system will “catch it.” So where’s the balance? There's a free masterclass happening on 28th May that's diving into this exact space. It’s framed for IT leaders, but it looks like anyone interested in practical insights and forward-thinking strategies would benefit. I’ve already signed up, so if you’re exploring this frontier too, maybe we’ll cross paths there. 👉(https://www.netcomlearning.com/webinar/Cybersecurity-Masterclass-How-AI-is-Redefining-Cyber-Defense?utm_source=devto.com)  ( 3 min )

In Part 1, I wrote about how I transitioned from working with a team to building solo. Once I made that decision, I needed to start somewhere - and for me, that was authentication. This post covers how I approached it using FastAPI, why I avoided localStorage, and how I made authentication declarative with a custom router. There are many ways to handle authentication, but I chose the most popular and relatively reliable approach: JWT auth. The spec generally assumes two endpoints: One to get an access + refresh token One to get a new access token if the previous one has expired The client needs to store these tokens somewhere and send them with each request—usually in headers. They're often stored in localStorage, which isn’t very secure. But I wasn’t as concerned with security (this isn’…  ( 5 min )

Imagine someone says a word out loud: “eight” or “ate”. To a human ear, they sound almost identical, most people couldn’t tell them apart without context. So how does an AI system like Google Assistant or Siri know what the speaker meant? That’s where the beauty of speech recognition and natural language processing (NLP) kicks in. Let’s understand it down step by step: When you speak, your voice creates vibrations in the air. A microphone picks up those sound waves and converts them into digital data, essentially, a stream of numbers that represent how your voice changes over time. But AI doesn’t listen to this data the way humans do. Instead, it transforms it into a spectrogram, a visual map of sound over time. It’s like a heatmap that shows: Pitch (high or low sounds) Intensit…  ( 5 min )

With Redis, your Spring Boot app can become faster and handle more traffic without breaking a sweat. This article will show you how to set it up step by step. However, before diving deep into Redis, we need to understand the concept of caching. Cache Cache is a fast, small, temporary storage frequently used by the computer or application to store and access important data. It stores data in a key-value format. By leveraging cache memory, we can minimize database calls, improving application performance since database queries are typically resource-intensive. The main objective of a cache is to speed up the retrieval of data by making a copy of the data in a location that can be accessed faster than the source or database. A cache is a small and fast, efficient memory space that an appli…  ( 9 min )

Nothing reveals a billionaire mindset quite like their spending habits. After all, to earn serious money, you first need to know why you want it. At first glance, it looks like madness - mushrooms on the orbit, banana art, tigers in Lambos. Crypto's wealthiest often seem to turn spreadsheets into spectacle - burning millions on stunts that feel more absurd than strategic. But what if that chaos is the clue? Maybe how they spend their wealth says more about how they earned it - and how they think. And maybe, just maybe, the ability to reprogram markets... comes with the urge to reprogram reality, too. 🛰 $55M to orbit the Earth’s poles (and grow mushrooms) 💰 A $2M treasure hunt - buried across the U.S. 🍌 The banana that became a $5M media weapon Yes.

About a month ago, I shared how my internship and final semester project came together perfectly, giving me the chance to dive into Laravel while building a platform to reduce food waste by connecting businesses with surplus food. I’m excited to say we’re nearly done! Over the past few weeks, our team has been polishing the app — fixing bugs, refining the user experience, and preparing for launch. The backend and database will be hosted soon, making the platform live and accessible. Looking Back at the Tech Stack: Backend: PHP Laravel — my internship experience gave me a strong foundation here, and I’ve deepened my understanding of scalable architecture, API development, and ORM relationships. Frontend: React — my teammate has built a clean, responsive UI that complements the functionality we’ve worked hard to develop on the backend, resulting in a seamless user experience across the platform. Database: MySQL — we designed the schema to handle complex relationships efficiently, especially for managing users, food listings, and organization profiles. This project has been both technically and personally rewarding. We’ve approached it like a real-world product, learning through every challenge. What’s Next: Deploying the backend and database online Final usability testing Gathering feedback for improvements If you’ve worked on something similar or have any tips for hosting and scaling Laravel apps, I’d love to connect and learn from your experience. Thanks for following along — more updates soon!  ( 3 min )

What breaking AI workflows taught me about the future of engineering. In traditional software development, when something breaks, you look at the logs. You dig into the stack trace, inspect variables, step through the debugger, isolate the bug. In AI-powered applications, that world is gone. When an LLM fails, there’s often no crash, no error, and no stack trace. Just a subtly wrong response. A hallucination. A weird behavior that’s technically correct but totally wrong for your user. Debugging becomes conversational. And that changes everything. In our product Linkeme, we rely on prompts to: Generate social media content Choose relevant CTAs Compose visual overlays And yet, some of the most frustrating bugs we faced early on didn’t come from bad code — but from poorly constructed prompts.…  ( 4 min )

Unlike traditional hardware firewalls that protect at the network edge, a software firewall is installed directly on host machines, virtual instances, or endpoints. Its primary job is to inspect, filter, and manage data traffic based on customized security rules. This digital guardian monitors both inbound and outbound connections, blocking suspicious activity and allowing only trusted communication to flow through. Whether it's a server, laptop, or cloud-based instance, a software firewall ensures that devices remain guarded—regardless of where they’re located. Software firewalls function by analyzing data packets using intelligent filtering techniques. They offer controls such as application-level monitoring, port and IP address restrictions, and real-time traffic evaluation. Administrat…  ( 4 min )

The recipe first Avoid using ObjectId Type for Ambiguous Typing System Across Tiers by favoring Strings instead. This will result in simpler backend types and DTOs that are reusable at the front end without requiring any special tools. The main disadvantage of this approach is a slight decrease in performance, as strings are larger than ObjectIds and can impact fast sorting operations. This scenario originated from a real application. It seems we followed the basic rules in different steps but ultimately failed. It would be great if we had changed the architecture at the start. Our application has a stack consisting of NestJS, Angular, and Mongoose, all written in TypeScript. We successfully implemented reusing typings across tiers, but it appeared complicated. Each tier had its own typing system, which could have been optimized. A clue to the problem is that the type of the primary field _id is ObjectId, a complex type present only on the backend. This made it unnatural for it to be used on both the frontend and backend. Some tools were implemented to reuse these types on ObjectId. New UI types were created, which seemed to improve the application's typing system. However, the application became convoluted, and we didn't want to research the case of using plain string IDs because we thought our approach was correct and it worked everywhere except for MeteorJS projects. If we refused to use the ObjectId type, we could eliminate the need for these tools, new UI types, and even DTOs that work on both frontend and backend. To test this idea, we created a separate project where I implemented the concept. The only disadvantage is the potential impact on MongoDB performance, which I couldn't measure. Additionally, we experimented with meaningful primary IDs where demanded custom solutions where string type is demanded.  ( 3 min )

Hi, I'm the developer of JavaFactory — a code generation tool that automates Java development using LLMs. Most AI code tools I've tried (like Cursor, Copilot, etc.) produce general-purpose code that's often unusable in real-world projects. They might write code quickly, but the result is: unpredictable, hard to maintain, and often completely wrong ( not usable ). So I built something different: A tool where I can explicitly define patterns and precisely control which classes are referenced. Yes, it takes some upfront work to define the rules. But the result? → Code that's testable, maintainable, and consistent with your actual architecture. In this demo, 400 lines of Java code (including tests) were generated in 20 seconds. All tests passed without manual edits. If you're tired of copy-pasting boilerplate and want AI that respects your structure — give this a try. 🔗 GitHub: link JetBrains Marketplace  ( 3 min )

Introduction In TypeScript, you can define custom shapes using type aliases or interface. But when it comes to choosing between them, many developers ask: "TypeScript Type vs Interface?" The answer is increasingly clear: use type. While both share similarities, type offers more flexibility, supports complex patterns, and aligns better with modern TypeScript and frameworks. In this guide, you'll learn the differences, strengths, and why type is the better default. Both type and interface define object shapes or function signatures: // Using type type Point = { x: number; y: number }; type SetPoint = (x: number, y: number) => void; // Using interface interface Point { x: number; y: number } interface SetPoint { (x: number, y: number): void } They look and behave similarly here, but the d…  ( 5 min )

In the ever-evolving world of software development, a seismic shift is underway. Developers, once primarily focused on writing code and building applications, are increasingly stepping into a new role: that of AI workflow designers. This transformation is not driven by a deliberate career pivot but by the rapid integration of artificial intelligence (AI) tools into the development process. These tools are reshaping how software is built, tested, and deployed, turning developers into "accidental architects" who orchestrate complex AI-driven workflows rather than solely crafting lines of code. This blog explores this evolution, examining how AI tooling is redefining developer roles, the skills required to thrive in this new landscape, and the implications for the future of software developme…  ( 9 min )

You may remember how much did others tell you to write your tests first, see them fail, and only write your production code after that? It's one of the craziest waste of time in software development, but not for the reasons you may think. The #1 reason your teachers, mentors and your community forced you to write unit tests first was this: get testable code. So, have you just accepted the implied message that if you don't write your tests first, your code will be untestable? Does it feel like you always need to make an extra effort to turn your code testable but you're not exactly sure why? Turns out, long story short, what makes code untestable is side effects. A function that changes global state, or the state of other objects, listens to global events, reads global state or the state o…  ( 5 min )

What Is Rate Limiting & Why It Matters webdev api security scalability architecture Rate limiting is about controlling how often a client can hit your app or API. It helps prevent abuse, reduce server load, and ensure fair access for everyone. Without it, one bad actor (or even an accidental loop) can overload your system. Every time a client makes a request, your server tracks how many requests they’ve made within a defined time window. If they exceed that limit, the server denies further requests — usually with a 429 Too Many Requests response. Clients can make a certain number of requests per fixed time period (e.g. 100 per minute). Simple but can lead to burst traffic at the start of each window. Spreads the request limit more smoothly over time. Prevents sudden spikes that fixe…  ( 4 min )

A Technical Evaluation of Milvus and Chroma DB In the rapidly evolving AI infrastructure landscape, vector databases have emerged as critical components for handling high-dimensional data. This analysis examines two prominent contenders—Milvus and Chroma DB—through the lens of enterprise readiness and developer experience, providing actionable insights for technical teams. Architectural Philosophy & Deployment Performance Benchmarks Milvus achieves 15,000 QPS on 768D vectors with 8ms p95 latency (32-node cluster) Chroma DB manages 2,300 QPS at 28ms latency (standalone instance) The gap widens with complex operations: Milvus' proprietary ANNS algorithms outperform Chroma's FAISS-based implementation by 40% in recall accuracy at 1M+ scale. However, Chroma's memory-mapped indexes demonstrate advantages for frequent schema modifications during development cycles. Ecosystem Integration Native PyTorch/TensorFlow data loaders Automated versioning for vector snapshots Grafana/Prometheus monitoring templates Chroma prioritizes LLM workflows with: LangChain integration out-of-the-box OpenAI embedding API compatibility Dynamic metadata filtering optimized for RAG pipelines Enterprise Readiness Cost Considerations Technical Recommendation Both platforms continue evolving—Milvus recently added GPU-accelerated indexing, while Chroma introduced hybrid scalar-vector search in Q2 2024. Technical leaders should evaluate these systems through the prism of their operational maturity and scalability requirements rather than seeking a universal solution. Note: All benchmark data reflects testing on AWS c6i.8xlarge instances with 500M 512D vectors unless otherwise specified.  ( 4 min )

Today, I dived into the world of CSS transitions, and I was excited to see how a small piece of code can make a website feel more smooth and interactive. In this post, I’ll share what I learned and how transitions work in CSS. CSS transitions allow you to change property values smoothly (over a given duration) instead of instantly. For example, instead of a button changing color immediately when hovered, transitions let that color change happen gradually. Here’s the basic syntax of a CSS transition: selector { transition: property duration timing-function delay; } property: The CSS property you want to animate (e.g., background-color, width, transform) duration: How long the transition takes (e.g., 0.5s, 1s) timing-function (optional): The speed curve (e.g., ease, linear, ease-in, ease-out, ease-in-out) delay (optional): The delay before the transition starts Hover Me .btn { background-color: #4CAF50; color: white; padding: 10px 20px; border: none; transition: background-color 0.3s ease; } .btn:hover { background-color: #2E7D32; } When you hover over the button, the background color changes smoothly from green to dark green in 0.3 seconds. You can transition multiple properties like this: .box { width: 100px; height: 100px; background-color: red; transition: width 0.5s, background-color 0.3s; } .box:hover { width: 200px; background-color: blue; } Only animatable properties can be transitioned (e.g., color, background-color, transform, opacity, width, height, etc.) Use transition: all if you want all animatable properties to transition — but use it carefully, as it can affect performance. Combine transitions with pseudo-classes like :hover, :focus, or :active for better interactivity. Learning CSS transitions opened my eyes to how much they can improve the user experience of a website. They're simple to use but make a big impact visually. I’m excited to explore more about animations using @keyframes and the animation property next!  ( 4 min )

Hello together, During my search with the AI Perplexity, I did not find good results to determine how to specify a number as a parameter or as a variable in Uniface. Although there is Uniface documentation [1] on this, it was not found. I do not understand why the AI cannot find the definition of a number in Uniface, even though there is a source for this. To make the best of it, I decided to write down my thoughts here. I do not consider myself a Uniface Senior or some kind of specialist in Uniface but rather as a beginner in this programming language. Regarding the question of how to represent a number in Uniface, the answer is the following: params Taken from the documentation of Uniface.

Is SaaS Really Dead? Several months ago, the internet was abuzz with the Microsoft CEO Satya Nadella saying, “SaaS is dead.” The conversation started with a question from Bill Gurley about whether Satya was worried that newer startups are building applications with an AI-first approach, which could obfuscate traditional infrastructure like Excel or CRM. Here is Satya’s response: I think, the notion that business applications exist, that's probably where they'll all collapse, right in the agent era because if you think about it, right, they are essentially CRUD databases with a bunch of business logic. The business logic is all going to these agents, and these agents are going to be multi repo CRUD Some people might assume he suggested that AI agents could or would replace SaaS. Howe…  ( 9 min )

In the world of data, change is the only constant. Over the last few decades, SQL (Structured Query Language) has reigned supreme as the go-to language for managing relational databases. Then came NoSQL, challenging the traditional norms with its flexibility and scalability. But today, a new player is emerging quietly yet powerfully: NewSQL. So, is SQL really dying? Is NoSQL losing its charm? And what exactly is NewSQL? Let’s break it down. The Era of SQL: A Quick Recap But as data exploded in volume, velocity, and variety — thanks to social media, IoT, and mobile apps — traditional SQL databases began to struggle with horizontal scalability and flexible schemas. The Rise and Struggles of NoSQL Schema-less design — ideal for unstructured or semi-structured data Lack of ACID guarantees The Death of SQL? The Silent Rise of NewSQL by Abhishek Shakya 🔑 Key Features of NewSQL Databases: Cloud-Native Architecture Real-Time Performance Data Integrity at Scale Simplified DevOps Real-World Use Cases Traditional SQL systems are struggling to keep up with modern demands. NoSQL tried to fill the gap but fell short in consistency and relational data handling. NewSQL is emerging as a modern solution, blending the best of both worlds: the familiarity of SQL and the power of NoSQL. The future isn’t SQL vs. NoSQL. It’s NewSQL — scalable, reliable, and SQL-compatible. If you’re building high-scale, mission-critical apps today, NewSQL might just be the quiet revolution you didn’t know you needed. ✅ Key Takeaways SQL is aging, but not obsolete. NoSQL brought scalability but lacked consistency. NewSQL offers the scalability of NoSQL with the reliability of SQL. NewSQL is powering modern, distributed, cloud-native applications.  ( 5 min )

If you’ve seen this in your console: “Access to fetch at ‘https://api.example.com’ from origin ‘https://yourapp.com’ has been blocked by CORS policy…” You’re not alone. Let’s dive into what CORS is, why it exists, and how to fix it. CORS? CORS (Cross-Origin Resource Sharing) is a browser-enforced security feature that prevents your frontend app (served from one origin) from accessing resources from another origin unless explicitly allowed by the server. This behavior stems from the Same-Origin Policy, which is designed to help prevent cross-site attacks. How CORS Works When your frontend makes a request to another origin, the browser sends an Origin header: Origin: https://myapp.com If the server responds with: Access-Control-Allow-Origin: https://myapp.com Preflight Requests For requests using methods like POST, PUT, or custom headers, the browser sends a preflight OPTIONS request to check if it’s safe. If the server doesn’t respond correctly, the browser cancels the actual request. Backend Config: Enabling CORS Here’s how to configure CORS in common backend frameworks: 🟢 Express.js const cors = require('cors'); 🐍 FastAPI app.add_middleware( https://myapp.com"], "], "], ❗ Common CORS Issues ❌ Missing Access-Control-Allow-Origin header ❌ Wildcard origin (*) used with credentials ❌ Server doesn’t respond to OPTIONS preflight 🧠 Dev Tips Use tools like http-proxy-middleware or Vite’s proxy config during local development. Never disable CORS in production — configure it properly. ✅ Final Thoughts CORS is not a bug — it’s a feature 🔐 Understanding how it works makes you a more confident full-stack developer and prevents hours of frustrating debugging. 💡 Got a CORS horror story or a helpful trick?

Article originally published here (image doesn't work well here) : https://alsohelp.com/blog/background-jobs-in-rails-8-are-delightful There's one thing I forgot to mention about my Rails 8 opinion last time : it's how background jobs are handled in Rails 8. Here's what it looks like on my current project : (image) Most web frameworks completely underestimate how background jobs are valuable. Honestly I always need a way to handle background jobs, on every new web project. Forgot password email ? => background task to send the email Clean image asynchronously ? => background task to clean the image And so on. IMHO A good way go see if a framework is mature enough is "are background jobs already included from day 1". Why it is so good with Rails 8? Because you don't have to care about : it's already included. From what I've read, it's not possible with other frameworks - outside Laravel. The Database is already backed The Dashboard is already included (!) And, of course, it's damn easy to hook any kind of job inside the framework itself. All I had to do is to protect the route, so that only the admin can view it. You don't have to care about the JS/CSS, because as long as you keep "propshaft" as gem, it will work. The beauty (again) is that I don't use propshaft myself. I use Vite. This is Rails deep integration : even if you don't use the default frontend management, external gem will work with your product. Of course "background jobs" means "take another thread than the one of the web server". So there's a tiny configuration locally (Thank you Matt Brictson for your bin/dev Rails 8 shine not only for the things previously mentionned, but also thanks to mission control.

This makes it easier to catch errors before you run your code. This makes working on big projects easier to manage and improves the coding process by making it smoother and more reliable. Luckily, it's not too hard to learn as long as you have a basic understanding of JavaScript. JavaScript was created by Microsoft and released in October 2012 How do I start? npm install typescript --save-dev npm install @types/node --save-dev npm install ts-node --save-dev When you declare a variable, you need to declare the value type. If you've created a variable called box that is a boolean, you will declare it as a boolean.…  ( 5 min )

我花4天时间接入支付，提交申请到通过只花了不到10分钟。这里分享一下实操和踩坑记录。 Stripe需要海外公司，paypal也需要有企业资质，其他的貌似要么需要企业身份，或者流程很麻烦，容易被拒。 我在开发(oeneo ai)的时候，一度卡在了支付这一块。国内独立开发者的独立站产品想要面向海外，收款支付是必须考虑的一块。 creem.io 是无意间在twitter上看到有人推荐，可能是因为刚起步，所以审核流程比较简单，并且支持支付宝直接收款，省去了银行卡这一步骤（也可以使用银行卡）。 我实际尝试下来确实很丝滑。 访问creem.io进行注册，支持谷歌帐号。注册完之后可以直接添加产品. 产品描述这里可以用markdown格式文本。产品类别只能选数字产品或者saas服务，支持一次性支付和订阅制。 下面这张图是产品支付页面详情，当时我截取这张图是为了看一下产品页面最后会怎么呈现给用户的。在下面这张图里，左侧上方“Basic Tier”是产品名字，中间是图片（可以省略），最下面是描述，大概就是这样一个布局。 产品填写页面有一个按钮 Price includes tax, 我理解是打开之后自动处理税务问题？（这一块不是特别清楚，有了解的大佬可以请教一下） 可配置的高阶功能： 设置免费体验时间，比如设置7天，那么7天内用户可无条件取消，7天以后才会真正扣款。 自定义变量： 这里主要用于付款成功之后发送给回调函数里的自定义变量，可以在代码里请求支付的时候设置 激活账户 这是最重要的一步，但是实际应该放在最后面，等网站开发得差不多了再申请。因为一旦申请，creem会对网站进行严格得审查，如果不通过，可能需要几个月时间才能第二次申请。 再申请之前需要仔细阅读creem的帐号review政策https://docs.creem.io/faq/account-…  ( 3 min )

I no longer think you should learn to code. Amjad Masad (CEO of Repit) I’ve been coding for about 16 years and working professionally for over a decade. After months of testing AI-assisted tools and “vibe coding” in early 2025, I can confidently say: that statement couldn’t be further from the truth. Sure, LLMs have pulled off some amazing things. And if you don’t know what it really takes to build working software, it’s easy to think the old way is now obsolete. But trust me, it’s not. Let’s take a look at things that have happened before, because this is not the first time we face a statement like this; back in the late 50’s - early 60’s COBOL emerged stating that it would allow people without traditional programming backgrounds ( like business professionals, managers, and analysts ) …  ( 10 min )

Concurrency VS Synchronization Synchronous code When code executes line by line in order, one thing at a time is called synchronous. It is simple, but sometimes might not be very efficient. func main() { // block 1 x := 10 x++ fmt.Printf("x = %d", x) // block 2 y := 20 y-- fmt.Printf("y = %d", y) } Check the code blocks in the above example. As you can see, the code lines in block 1 should execute in order. The code lines in block 2 should also execute line by line. But blocks 1 and 2 have no dependency on each other. So, we can run them separately on two CPU cores. This is called running in Parallel. It increases efficiency. In Golang, it is easy to write concurrent code. func main() { // some code go funcName() // rest of the co…  ( 6 min )

Problem description & analysis: The ID field of a certain database table is used for sorting, the logic field is used for conditional judgment, and val is used for segmented accumulation. Task: Now we need to add a calculated column output. When logic==true, output is set to 1. Otherwise, output is accumulated and the value is the output of the previous row + val. SQL： with table1 as ( SELECT *, countif(logic) over win1 as logic_run FROM example_data window win1 as (order by id rows between unbounded preceding and current row) ) SELECT *, sum(val) over win2 as sum_over, sum(if(logic,1,val)) over win2 as output from table1 window win2 as (partition by logic_run order by id rows between unbounded preceding and current row) SQL requires multiple window functions and subqueries to indirectly implement cumulative calculations, which is cumbersome in terms of code.

1. Background and Motivation Although Google Guava’s EventBus is already quite convenient, I wanted to build something more extensible — a component that not only functions as an EventBus but also supports delayed events out of the box. While exploring the Apache DolphinScheduler project, I found its built-in eventbus component to be a well-written and efficient solution. It inspired me to extract and adapt it for use in our own business systems. Thanks to DolphinScheduler’s open-source nature, this component can now be conveniently reused with minimal overhead. Let’s walk through how to extract it and run a working demo. First, we define a base interface for all events: public interface IEvent { } To support delayed execution, we introduce an abstract class AbstractDelayEvent that exte…  ( 5 min )

Em programação, um dicionário (também chamado de mapa ou hashmap) é uma estrutura de dados que armazena dados em pares de chave-valor, onde as chaves são usadas para acessar os valores. É como uma lista onde os elementos são acessados por nomes (chaves) em vez de índices numéricos. As chaves do dicionário são usadas como índices para localizar o valor associado. Ao invés de percorrer a coleção inteira para encontrar um valor, o dicionário usa a chave para calcular um índice na tabela hash. Essa chave é passada para uma função hash, que gera um valor numérico (o índice na tabela hash). Para exemplificar, vamos armazenar o valor do quilograma de cada fruta dentro do dicionário. Tabela hash: Em JavaScript, o objeto Map armazena pares chave-valor preservando a ordem de inserção e aceita qu…  ( 5 min )

Pseudo-element yang Wajib Diketahui Pseudo-element secara bahasa artinya Element Semu, alias element yang samar atau tersembunyi. Pada beberapa elemen HTML ada yang membawa elemen semu seperti elemen input yang membawa elemen semu placeholder. Kalau kita memberikan styel color ke input, maka style tersebut akan diterapkan ke hasil inputan kita dan bukan ke placeholder. Disini lah peran pseudo-element sebagai selector ke placeholder. Pseudo-element ciri khasnya diawali dengan titik dua dua di depan. Jadi untuk placeholder selectornya menjadi ::placeholder.

Closures in JavaScript occur when a function retains access to variables from its lexical scope, even after the outer function has finished execution. This allows functions to "remember" values and maintain state. 🔹 Simple Example: function outerFunction() { let counter = 0; // Local variable return function innerFunction() { counter++; // Inner function remembers 'counter' console.log(counter); }; } const increment = outerFunction(); // Returns innerFunction increment(); // 1 increment(); // 2 increment(); // 3 🔹 Explanation: outerFunction() defines a local variable (counter). innerFunction() modifies counter, but the outer function has already executed! However, innerFunction() retains access to counter due to closure behavior. Each call to increment() updates the retained counter, demonstrating persistent state. Closures are useful for encapsulation, maintaining private variables, and creating efficient event handlers. 🚀  ( 3 min )

1. Why Build a Message Queue from Scratch? Message queues are the unsung heroes of distributed systems—think of them as traffic cops directing data between services. They decouple apps, handle async tasks, and smooth out traffic spikes. NSQ, a lightweight, Go-based queue from Bitly, caught my eye for its simplicity and speed, making it perfect for small-to-medium projects. So why rebuild it? Two reasons: Learning by Doing: Nothing beats rolling up your sleeves to grok how queues tick. Customization: Need priority messages or a leaner persistence layer? DIY lets you tweak it your way. This tutorial walks you through coding an NSQ-inspired message queue in Go. It’s aimed at devs with 1-2 years of Go experience—folks comfy with goroutines and channels but itching to tackle distributed s…  ( 9 min )

Key takeaways: Bitcoin futures open interest hit a record $72 billion, signaling rising use of leverage among institutional investors. $1.2 billion in shorts at $107,000 to $108,000 are at risk of liquidation, boosting BTC’s breakout odds. The aggregate open interest in Bitcoin (BTC) futures surged to a record high on May 20, raising questions about whether bearish positions are now at risk. Despite repeated failures to break above the $107,000 level since May 18, the sheer volume of leveraged positions could propel Bitcoin to a new all-time high.

The two organizations are considered competitors in the sector of decentralized finance (DeFi). “When an organization continuousl…

Key takeaways: An end-of-month Bitcoin price close above $102,400 would set the highest monthly close ever, proving the bull market continues at a rapid pace. Over $3 billion in Bitcoin short positions are vulnerable above $107,000, creating a “liquidation magnet” that could send BTC price to new highs. Bitcoin (BTC) is 11 days from potentially setting its highest monthly candle close in history.

US Securities and Exchange Commission (SEC) Paul Atkins appeared before lawmakers in one of his first hearings since becoming chair of the financial regulator, addressing questions about his plans for the cryptocurrency industry. In a May 20 hearing discussing oversight of the SEC, Atkins reiterated his pledge to make regulating digital assets a “key priority” while chair. In response to questions from North Carolina Representative Chuck Edwards, the SEC chair did not directly answer how much of the regulator’s funds were used to support the crypto task force headed by Commissioner Hester Peirce, and said its findings were “still under development.” “We should be having something here in the next few months with proposed steps forward,” said Atkins in response to the task force’s first report.  The SEC chair’s appearance at the oversight hearing was one of his first since being sworn into office in April. Nominated by Donald Trump, Atkins, also a former commissioner, was seen by many lawmakers and those in the digital asset industry as someone who could radically change the SEC’s approach to crypto.  This is a developing story, and further information will be added as it becomes available.

Opinion by: Hatu Sheikh, founder of Coin Terminal Although blockchains and DApps are critical, crypto industry stakeholders often prioritize applications based on adoption principles and revenue distribution. DApps won't function without their underlying chains. The markets must uphold blockchains for long-term value generation. The value perspective is wrong  Blockchains and DApps should work collaboratively to coordinate their functions for better usability. Instead, analysts create a binary between chains and DApps based on Web2's structural frameworks. In “Fat Protocols,” Joel Monegro argued that value within the internet stack comprises "thin" protocols and "fat" applications. In other words, investing in the underlying protocol technologies like TCP/IP, HTTP, and SMTP gives lower ret…

US Senate Democrats are getting flak after they helped move stablecoin legislation ahead for discussion on the Senate floor. On May 19, 16 Democratic senators broke from the party line to pass a motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Some of the same Democrats had held up the bill in early May when they withdrew support, citing corruption concerns over President Donald Trump’s cryptocurrency dealings. The bill’s opponents hailed lawmakers’ refusal to support it but were soon taken aback when the senators reversed their position. The lightly amended legislation contained no provisions regarding World Liberty Financial, the Trump family’s crypto venture. Some activists have said that the Democrats supporting the bill should be ousted in the u…

Robinhood submitted a 42-page proposal to the US Securities and Exchange Commission (SEC), calling for a national framework to regulate tokenized real-world assets (RWAs). The brokerage is seeking to modernize financial infrastructure by making tokenized assets legally equivalent to their traditional counterparts and enabling compliant onchain settlement, Forbes reported on May 20. In the proposal, Robinhood also revealed plans for creating the Real World Asset Exchange (RRE), a trading platform offering offchain trade matching and onchain settlement for efficiency and transparency. Robinhood is advocating for uniform federal standards to replace the patchwork of state-level securities regulations that currently apply. The platform would also integrate Know Your Customer (KYC) and Anti-Mon…

India’s Supreme Court has questioned the government’s lack of regulatory clarity on cryptocurrencies despite imposing taxes on digital assets like Bitcoin. According to Indian legal news outlet LawChakra, the country’s Supreme Court expressed concern over the growing use of Bitcoin (BTC) and other cryptocurrencies while remaining largely unregulated. “This is a whole parallel economy running with such coins and is a danger to the economy of the country,” Justice Surya Kant reportedly said during a recent hearing related to an ongoing investigation into a Bitcoin transaction. Kant further highlighted that while the government has implemented crypto taxation, it has failed to regulate the space. “If you can tax it at 30%, also please regulate it as you have recognised it by taxing it,” the j…

Binance has filed a motion to dismiss a $1.76 billion lawsuit brought by the FTX estate, accusing the defunct crypto exchange of trying to deflect blame for its own failure. Filed on May 16 in the Delaware Bankruptcy Court, Binance’s legal team called the suit “legally deficient,” stating that FTX’s collapse was not triggered by market manipulation or hostile action but by internal misconduct. “Plaintiffs are pretending that FTX did not collapse as the result of one of the most massive corporate frauds in history,” the filing said, pointing to Sam “SBF” Bankman-Fried’s conviction on seven counts of fraud and conspiracy. FTX’s estate alleges that Binance received billions in crypto during a 2021 buyback deal, funded improperly with customer assets. Binance rejects this claim, stating that “…

Key takeaways: Bitcoin is nearing a golden cross that led to 45–60% price rallies in the recent past. Fundamentals like rising M2 supply and easing trade tensions support a bullish outlook. Bearish divergence and overbought conditions show there’s still a risk of BTC falling below $100,000.

A recent data breach at crypto exchange Coinbase has raised concerns about user safety after hackers gained access to sensitive information, including home addresses. Coinbase, the world’s third-largest cryptocurrency exchange, confirmed that less than 1% of its transacting monthly users were affected in an attack that may cost the exchange up to $400 million in reimbursement expenses, Cointelegraph reported on May 15.

South Korea’s Democratic Party leader Lee Jae-myung proposed creating a stablecoin tied to the Korean won to prevent capital outflows and strengthen national financial sovereignty. Speaking during a recent policy discussion, Lee argued that a won-based stablecoin would allow South Korea to retain wealth domestically while reducing reliance on foreign-issued digital assets like USDt (USDT) and USDC (USDC), according to The Korea Herald. Currently, South Korean law prohibits the issuance of domestic stablecoins, forcing local exchanges to rely on US dollar-based alternatives. Between January and March, crypto exchanges in the country recorded 56.8 trillion won ($40.8 billion) in asset outflows, nearly half of which were linked to foreign stablecoins, the report said. “We need to establish a …

The $330 million attack: A stark reminder of social engineering’s power A major crypto theft has sent shockwaves through the industry, with $330 million worth of Bitcoin (BTC) stolen. Experts say this was a social engineering attack and not a technical hack.  Investigations led by blockchain analyst ZachXBT suggest the victim was an elderly US citizen who was manipulated into granting access to their crypto wallet. On April 28, 2025, ZachXBT detected a suspicious transfer of 3,520 BTC, worth $330.7 million.  The stolen BTC was quickly laundered through more than six instant exchanges and converted into the privacy-oriented cryptocurrency Monero (XMR). Onchain analysis shows the victim had held over 3,000 BTC since 2017, with no previous record of s…

Through their court-appointed Litigation Oversight Committee (LOC), Genesis creditors claim that over a million digital coins — worth about $2.1 billion — were funneled away, even as Genesis edged toward collapse. As per the complaint, Genesis creditors are still owed around $2.2 billion worth of…

The US Securities and Exchange Commission’s sole Democratic Commissioner has said the agency is “playing a game of regulatory Jenga” with its approach to the crypto industry and market regulation under the Trump administration. In May 19 remarks at the SEC Speaks event, Commissioner Caroline Crenshaw cautioned against what she described as a dangerous dismantling of “discrete but interrelated rules” on crypto and the wider market. She likened market stability to a “Jenga tower” that the agency’s rules had “carefully developed over the years,” which could topple if some rules were removed. In addition to a lamentable loss of staff, Crenshaw said the SEC has used staff guidance to effectively reverse rules without proper analysis or public comment, particularly around crypto “Our statements…

Crypto exchange Binance has asked a US federal judge to send all members of a class-action lawsuit alleging it sold securities to arbitration, arguing that the group waived their ability to form a class action under the company’s terms. The exchange said in a May 16 filing to a New York federal court that its terms of service, which it claimed the class group agreed to, has a clause that users agree to arbitrate all claims, along with a clause preventing users from launching class actions against the crypto exchange. “The Court should hold that Plaintiffs are required to arbitrate claims that accrued after Feb. 20, 2019, even if the Court adheres to its initial decision as to claims that accrued before then and that the class-action waiver in the 2019 Terms of Use is enforceable for all of…

Jamie Dimon, the CEO of JPMorgan, said his bank will soon allow its clients to buy Bitcoin, but it won’t custody the cryptocurrency. “We are going to allow you to buy it,” Dimon said at JPMorgan’s annual investor day on May 19. “We’re not going to custody it. We’re going to put it in statements for clients.” CNBC reported that Dimon also remarked on his long-held skepticism about crypto assets, pointing to their use in money laundering, sex trafficking and terrorism. “I don’t think you should smoke, but I defend your right to smoke. I defend your right to buy Bitcoin,” he said. Michael Saylor comments on Dimon’s announcement. Source: Michael Saylor JPMorgan will offer clients access to Bitcoin (BTC) exchange-traded funds (ETFs), CNBC reported, citing sources familiar with the situation.

Spot Bitcoin ETFs in the US have seen significant adoption, with almost $42 billion in total aggregate inflows since they launched in January 2024.  Dimon’s Bitcoin bashing history Dimon has long been skeptical of Bitcoin, labeling it a scam that he had no interest in buying in 2018 and calling it “worthless” during the 2021 crypto bull market. “I’ve always been deeply opposed to crypto, Bitcoin, etc.,” he said during a Senate Banking Committee hearing in 2023. “The only true use case for it is criminals, drug traffickers, money laundering, tax avoidance.” “If I were the government, I’d close it down,” he said. At the 2024 World Economic Forum in Davos, Switzerland, Dimon said Bitcoin “does nothing. I call it the pet rock,” which came after the asset topped $100,000 for the first time.   Magazine: Arthur Hayes $1M Bitcoin tip, altcoins ‘powerful rally’ looms: Hodler’s Digest

The US Senate has voted to advance a key stablecoin-regulating bill after Democrat Senators blocked an attempt to move the bill forward earlier in May over concerns about President Donald Trump’s sprawling crypto empire. A key procedural vote on the Guiding and Establishing National Innovation for US Stablecoins Act, or GENIUS Act, passed in a 66-32 vote on May 20. Several Democrats changed their votes to pass the motion to invoke cloture, which will now set the bill up for debate on the Senate floor. Republican Senator Cynthia Lummis, one of the bill’s key backers, said on May 15 that she thinks it's a “fair target” to have the GENIUS Act passed by May 26 — Memorial Day in the US. The US Senate voted 66-32 to advance debate on the GENIUS stablecoin bill. Source: US Senate The GENIUS Act was introduced on Feb. 4 by US Senator Bill Hagerty and seeks to regulate the nearly $250 billion stablecoin market — currently dominated by Tether (USDT) and Circle’s USDC (USDC). The bill requires stablecoins be fully backed, have regular security audits and approval from federal or state regulators. Only licensed entities can issue stablecoins, while algorithmic stablecoins are restricted. Several Democratic senators withdrew support for the bill on May 8, blocking a motion to move it forward, citing concerns over potential conflicts of interest involving Trump’s crypto ventures and anti-money laundering provisions. Related: Circle plans IPO but talks with Ripple, Coinbase could lead to sale: Report The bill was revised soon after to receive enough bipartisan support to proceed to a vote.

The pandemic drove a considerable increase in fully remote teams, which made card games quite difficult to organize. Therefore, in 2022, Grant Ongers was willing to bet a dinner at a fancy vegan restaurant that his former colleague Toby Irvine wouldn't be able to build a fully fledged and online game engine based on the game Cornucopia (from the OWASP® Foundation) over the weekend. A weekend later, Copi was born, and Grant lost the bet. Elixir and Phoenix, 3 years later, Copi is nearing almost 10.000 monthly users. You can read more about Toby's story on the Secure Delivery Blog. There is now a new release of OWASP Cornucopia 2.2 to celebrate a new milestone in the project's history. https://github.com/adamshostack/eop Finally, if you have stringent security policies that don't allow you…  ( 5 min )

XAUUSD is a symbol used in Forex trading to indicate the number of US dollars needed to buy one ounce of gold. Other abbreviations such as EURUSD indicate the exchange rate of national currency pairs while XAUUSD shows comparison between the price of the precious metal and the rate of the US dollar. It is possible to buy gold as a physical commodity at banks or from dealers. Gold is often used by governments that have a large gold reserve to protect the value of their currency; that’s why it is traded on the Forex market. I chose XAUUSD due to high volume of trading together with an extensive amount of historical and real-time data available. It is also not specific to any one nation, economy, or business; rather, it is globally essential. It is more intriguing examining how the …  ( 5 min )

A gestão de projetos é, cada vez mais, um pilar técnico dentro das organizações modernas. Não adianta ter um time que domina frameworks de ponta ou uma stack atualizada se os projetos caminham sem clareza, priorização e cadência. Em muitos casos, não é a tecnologia que trava o time é a ausência de uma gestão estruturada. Empresas como o Nubank, por exemplo, entenderam desde cedo a importância de ciclos curtos e times autônomos. Ao adotar uma variação do modelo Agile, com squads multidisciplinares e foco em entregas iterativas, conseguiram escalar seus produtos mesmo utilizando uma linguagem funcional como Clojure, considerada pouco comum no mercado. Não foi apenas a escolha da linguagem que impulsionou o sucesso, mas como os projetos foram organizados para extrair o máximo do time técnico.…  ( 4 min )

Alright, folks, welcome back to the series of Model Context Protocol! In Part 2: Looking Under the Hood, we took a delightful little spelunking trip into the guts of MCP, marveling at its STDIO and SSE transport mechanisms, and even peeked at the shiny new OAuth 2.1 and Streamable HTTP features. It all looked so promising, so... functional. Well, today we're trading our hard hats for tinfoil ones. We're about to wade into the swampy, infested, and quite frankly, terrifying security landscape of MCP. If Part 2 was about how MCP works, Part 4 is about how it breaks... spectacularly.

Built My First React Native App — An Internal Admin Tool for Formant Took a big step forward today. I built my first React Native app — a custom internal admin tool for managing blog content and media on formant.ca, my personal dev and music studio site. It’s not public, but it’s functional and live on my own Android device. I can now post updates, write drafts, and manage media directly from my phone. Set up a fresh React Native project from scratch Built a modular interface without any templates or generators Integrated Firebase Auth and handled some runtime quirks with Hermes Deployed locally and tested the app on-device It’s the first part of a broader toolset I’m building to keep Formant fully in my hands — no third-party platforms, no content lock-in.

Azure App Service - Hidden Network Trap Dušan Knežević ・ May 19 #programming #azure #cloud #network  ( 2 min )

Introduction A few weeks ago, I was asked to investigate intermittent database connection failures affecting one of two Azure App Service instances. Both instances shared the same App Service Plan for a client, and—crucially—had been running smoothly for five weeks before these issues appeared. Interestingly, all development ("lower") environments were unaffected; only the production environments were experiencing failures. Each app used its own Azure Storage account and Azure SQL database. Both App Services were in production. The first app was failing to connect to its storage account, while the second was failing to connect to its Azure SQL database. The logs didn’t reveal anything unusual—just connection failures. Since the apps were already down, I decided to restart them, hoping a …  ( 4 min )

When working with data, we are familiar with two tools: SQL and Python. Both are important for data professionals, but they serve different purposes. So let me break down which one should you use for querying and cleaning data. Querying Data: SQL is the best. reasons is that: Optimized for Databases – SQL is built specifically for querying structured data in relational databases (PostgreSQL, MySQL, BigQuery, etc.). Faster Queries – Databases are optimized for SQL, making it much faster than Python for filtering, aggregating, and joining tables. Simple Syntax – for example when one needs sales data from last month? SQL is direct: SELECT customer_id, SUM(amount) FROM sales WHERE date >= '2024-01-01' GROUP BY customer_id; Works with big Datasets – SQL databases handle billions of rows effi…  ( 4 min )

Photo by Ryan Quintal on Unsplash Angular mudou e continua mudando... Antes, um componente precisava ser declarado dentro de um NgModule para "sobreviver". Agora, ele simplesmente existe — de forma autônoma. Sempre tive aquela analogia de que os componentes no Angular viviam dentro de caixas chamadas módulos, que por sua vez se encaixavam em outras caixas maiores, como o AppModule. No fim, tudo era uma grande construção de peças interconectadas, como um LEGO® bem estruturado. Mas tudo isso começou a mudar a partir da versão 14 do Angular, quando os chamados componentes autônomos (standalone) foram introduzidos como uma funcionalidade experimental. Na versão 15, essa abordagem foi estabilizada e passou a fazer parte oficial do ecossistema. E com isso vem mais uma linha de aprendizado, pois…  ( 4 min )

After the recent post by DHH about “vibe coding”, I too felt the urge to take a plunge into the “vibe coding” pool as to what it is, and why it’s appealing. The term “vibe coding” was coined by Andrej Karpathy, who was also a founding member of OpenAI. As Karpathy describes, vibe coding is when you don’t think about code, you blindly trust whatever LLMs throws at you, and you vibe your way into building something. This approach to software development is made possible by how far language models have come (like Claude Sonnet), along with the rise of AI-powered editors such as Cursor and GitHub Copilot in VS Code. Vibe coding or not, coding with AI is quickly becoming the new default. Traditional software development has a steep entry barrier. You need to learn a programming language, grasp …  ( 4 min )

We've twisted the word serverless into something vague. These days, serverless usually just means "I don't manage the infrastructure, someone else does." Which is fine. But it's also not the full picture. Because if we take the word literally (no server process to run, configure, or scale) then one database has quietly been the most serverless of all for over 20 years: SQLite. It doesn't run in the cloud. It doesn't need to connect to a remote API. It doesn't even require a boot-up process. It just works. And it's criminally underrated. Let's break this down into two flavors: This is the popular kind. You write your application and connect to a database that is fully managed by a third party. You don't worry about patching, scaling, or provisioning. Some examples: Firebase DynamoDB Neon Pl…  ( 5 min )

We are likely witnessing a quiet crisis in our technical teams. While we celebrate the productivity gains of AI tools, a more insidious process probably unfolds beneath - the surface—the systematic erosion of our fundamental technical capabilities. This is not pure speculation or technophobic fear-mongering; it is the reality playing out. The pattern is alarmingly consistent. A team adopts AI tools to enhance productivity. Initial results are impressive: faster code generation, quicker troubleshooting, more efficient documentation. Management celebrates the metrics.

Implementing a Custom Reactive Library in Vanilla JS Introduction In recent years, the demand for reactive programming paradigms has skyrocketed. Libraries and frameworks like React, Vue, and Svelte dominate the landscape, each tailored to enable developers to create dynamic user interfaces with a reactive data flow. However, the principles underlying these frameworks can be distilled into fundamentally simple concepts that can be implemented in vanilla JavaScript. This article aims to explore the implementation of a custom reactive library, examining its architecture, intricacies, and performance considerations. The roots of reactive programming can be traced back to the late 1990s and early 2000s. Initially conceptualized for event-driven applications, reactive programming u…  ( 6 min )

We all know the feeling. Suddenly your train of thought derails. You try to get back into flow, but it’s gone. Welcome to modern software development, where real productivity isn’t about working harder—it’s about working asynchronously. The Problem With Synchronous Everything Here’s the core issue: Synchronous communication assumes everyone is available at the same time. The difference is massive. If your team relies too heavily on live calls, pings, or "quick syncs," here’s what happens: Developers are constantly pulled from deep work Time zone mismatches create delays Pressure builds to be “always available” Creative thinking suffers due to fragmented focus As a developer, your job is to think clearly and build complex systems.

As your cybersecurity toolkit grows, one concept becomes increasingly important—aggregation. Logs from a single server tell a story, but when you start working with networks of devices, cloud services, containers, and multiple endpoints, you quickly realize that analyzing one log file at a time is not enough. You need a way to bring those logs together, sort through the noise, and create a unified view of what is happening across your environment. That is where log aggregation comes into play. By collecting and combining log data from multiple sources, you can detect patterns, respond faster to incidents, and make informed decisions. In this article, we will explore how to build simple but effective log aggregation workflows using Python, and why it is a powerful step forward in your secur…  ( 6 min )

🚀 What is the Model Context Protocol (MCP)? The Model Context Protocol (MCP) is an open standard introduced by Anthropic that aims to simplify how AI applications—like chatbots, IDE assistants, or custom agents—connect with external tools, data sources, and systems. Before USB, connecting devices meant dealing with dozens of ports and drivers. Similarly, integrating M different AI apps with N different tools used to require M × N custom integrations—a huge development burden. MCP changes that to an M + N model: Tool creators only need to build 1 MCP server per tool App developers only need to build 1 MCP client per application 🧩 How it works MCP follows a client-server architecture: Hosts: AI applications the user interacts with (e.g., Claude, an IDE, a custom agent) Cli…  ( 4 min )

I came across The Cloud Resume Challenge by Forrest Brazeal while studying for my AWS CCP exam, and without much thought, I added the website to my bookmarks. I was certain that at some point, I would take on the challenge, as it seemed like a great opportunity to gain hands-on experience with AWS. And… I did — after passing my exam, I started working on the project. At the very beginning, I had to set up my AWS personal development environment to ensure that my account (and my wallet!) was properly protected. To do so, I decided to use AWS Organizations. I created a "root" AWS account and set up an AWS Organization with an Organizational Unit (OU) inside it. Under the OU, a new AWS account was created, and this was the account used to create any resources related to the project. At this s…  ( 5 min )

Web UX is having a moment. Not because of a new JavaScript framework (for once), but because of something much more fundamental: natural language as the interface itself. In early 2025, Microsoft introduced NLWeb, a project that brings conversational AI directly into websites via simple HTML attributes and JavaScript APIs. It's a shift that front-end developers and designers alike should be paying close attention to — because it fundamentally changes how users interact with the web. NLWeb is a Microsoft initiative designed to embed natural language interfaces directly into web experiences. Instead of rigid search bars or click-driven navigation, users can interact with a site using conversational queries — like asking a clothing store’s site, “Show me something under \$50 that's good for s…  ( 5 min )

The Singleton pattern is one of the most fundamental design patterns in software engineering, and it has several practical applications in frontend development. While often debated (as overuse can lead to issues), when applied judiciously, the Singleton pattern can solve specific problems elegantly in client-side applications. A Singleton is a design pattern that restricts a class to a single instance and provides global access to that instance. In JavaScript/TypeScript terms, it ensures that no matter how many times you try to create an instance of a class, you always get the same instance. Modern frontend frameworks often use Singleton-like patterns for state management: // Redux store (typically a Singleton) import { createStore } from 'redux'; import rootReducer from './reducers'; con…  ( 5 min )

Traditional AI evaluation methods are struggling to keep pace with the rapid evolution of language models. Metrics like BLEU and ROUGE scores, which rely on deterministic measurements, fall short when assessing the creative, non-deterministic outputs of modern AI systems. Enter "LLM as a judge" — an innovative approach that uses language models themselves to evaluate AI outputs. This method harnesses the sophisticated understanding capabilities of LLMs to provide nuanced, context-aware assessments that better match the complexity of today's AI systems. Unlike conventional evaluation methods, LLM judges can adapt to varied contexts and offer detailed, qualitative feedback that more closely resembles human judgment. Language model judges function by implementing sophisticated prompt engineer…  ( 4 min )

Cloud cost breakdowns don’t have to break you. Here’s a beginner-friendly dev's guide to FinOps—fun, practical, and a little too real. You know that feeling when your cloud bill hits and you stare at it like it’s written in Elvish? Yeah, me too. I used to think cloud billing was just an annoying backend detail. "It scales, right? That’s the dream!" Until I realized we weren’t scaling—we were leaking money like a perforated S3 bucket. That’s when I met FinOps. Not a tool. Not a vendor. A mindset. A practice.

One of the most valuable and underestimated tools in cybersecurity is the log parser. Every system, application, and network device generates logs, and hidden within these logs are the clues to attacks, misconfigurations, and system health issues. The challenge is not collecting logs, but making sense of them efficiently. That is where Python steps in as a powerful ally. In this article, we will walk through the principles of building a custom log parser using Python. Whether your logs come from web servers, firewalls, or authentication systems, being able to process and analyze them is essential for anyone interested in security operations, threat hunting, or incident response. To begin with, it is important to understand what logs really are. At their core, logs are just text files fille…  ( 6 min )

Today was a solid day — tackled 4 more problems that deepened my understanding of hashing and stack-based logic. Covered some variety: hash frequency, prefix sum tricks, and even a stack-based temperature-wait problem. Here’s the breakdown: Problem: Prior to being passed to your function, nums is possibly rotated at an unknown pivot index k (1 <= k < nums.length) such that the resulting array is nums[k], nums[k+1], ..., nums[n-1], nums[0], nums[1], ..., nums[k-1]. For example, [0,1,2,4,5,6,7] might be rotated at pivot index 3 and become [4,5,6,7,0,1,2]. Given the array nums after the possible rotation and an integer target, return the index of target if it is in nums, or -1 if it is not in nums. You must write an algorithm with O(log n) runtime complexity. Link to problem: https://leetco…  ( 4 min )

TL;DR: Higher-Order Functions (HOFs) are functions that receive or return other functions. They’re key to functional programming, widely used in React, map(), filter(), and more. They help abstract repetitive logic, making your code cleaner, testable, and elegant. Classic examples: setTimeout, Array.map(), Array.filter(), function factories. Higher-Order Functions (HOFs), or First-Class Functions, became a hot topic in JavaScript over the last few years — largely thanks to functional programming principles and React. But despite the intimidating name, HOFs are actually pretty simple. They can be defined as: Functions that takes one (or more) functions as parameters, or Functions that return another function But what’s the point of passing a function as a parameter?

Se você já trabalhou com APIs em .NET, provavelmente já ouviu falar sobre Middlewares. Mas afinal, o que são e por que são tão importantes? Neste artigo, vamos explorar o conceito de Middlewares no contexto de APIs .NET, entender como eles funcionam e ver exemplos práticos de como utilizá-los. O que são Middlewares? Middlewares são componentes que formam o pipeline de processamento de requisições em uma aplicação .NET. Eles são responsáveis por lidar com solicitações HTTP (requests) e respostas HTTP (responses), permitindo executar lógicas antes e depois que uma requisição chegue ao seu endpoint final. Pense em um middleware como uma "camada" que a requisição passa antes de chegar ao seu destino (e também na volta, quando a resposta é enviada ao cliente).

I completed General Assembly’s Web Developer Immersive in 2016. Back then, the curriculum focused on Vanilla JavaScript, jQuery, raw Ruby, Ruby on Rails, and the MEAN stack (MongoDB, Express, AngularJS, Node). At the time, everything moved at breakneck speed—and while we covered a lot, I don’t think the fundamentals ever had time to really sink in. What I did admire was the program’s emphasis on building and deploying projects. You were thrown into the deep end—forced to wrestle with unfamiliar concepts and figure things out as you built. Pre-LLM, that approach made sense. You just pushed through and got something working. Whether that led to long-term understanding, though, was a different story. It wasn’t until I enrolled in CSMC 203: Introduction to Programming at Montgomery College that things finally began to click. That foundational class helped me breeze through CSMC 206: Python Programming, and from there, everything felt more grounded. Eventually, I transferred to the University of Illinois Chicago to finish my CS degree. Being at a large public university, many professors rely on autograders to evaluate code. Imagine your first programming project being run through HackerRank or LeetCode-style tests without ever really being shown how to solve a problem. It’s easy to see how that could be discouraging—maybe even enough to push someone out of the field entirely. And UIC? They pile on the homework, especially in the engineering department. There isn’t much space to breathe, let alone learn deeply, until the semester ends. I’ve been balancing work and school for a while now, and I finally have the time and mental bandwidth to prove what I’m capable of—not as a cog in an assembly line, but as a developer who builds with intention. Over the coming months, I plan to build and share 12 projects that demonstrate why I’m a senior developer—and why I’m qualified for just about any role I apply to.  ( 3 min )

In computer systems, username and password has become a widely used way to authenticate users. The evolution of password storage and authentication methods has gone through various stages to enhance security and protect user credentials. Here's an overview of the progression from plain text passwords to using Secure Remote Password (SRP) and the key concepts at each stage: Plain Text Passwords: In the early days of computing and network authentication, passwords were often stored in plain text on servers. This means that when a user entered their password, it was stored exactly as entered. The main problem with plain text storage is that if the server is compromised, attackers can easily obtain the passwords, potentially leading to unauthorized access to user accounts.

For several years form-data.com offered a forms-backend as a service, for people building their own static forms. Creating a form builder was an idea that I played with for a long time. However, as a developer I didn’t like most of the form builders out there. It always feels like I have to fill-in a (really complicated) form just to create a form. What I ended up with was a text-to-form builder. On the left you write simple text descriptor, and on the right you get a form. And of course, as with any product these days, you can just ask the AI to write it for you. Publish the form is simple, and you’ve got yourself a hosted form. And the backend gets all you’d expect from a forms the backend, including spam filter, email notifications, auto-response emails and integrations. I’d really appreciate if you give it a go and share any feedback - the studio is open without registration, and if you want to publish you need to signup without credit-card, and you get 100 free credits.

Written by Frank Joseph✏️ API documentation is more than a technical formality; it’s a make-or-break component of your API’s success. In Merge’s guide to API evaluation criteria, “comprehensive data” ranked as the second most important factor when evaluating an API, right behind consistent data format. That’s no coincidence: clear documentation is what makes an API usable in the first place. In this tutorial, we’ll explore why API documentation matters, recent trends in the space, and how to build great docs from scratch using Docusaurus — including writing components for HTTP methods step by step. APIs (Application Programming Interfaces) are the backbone of modern software development. Whether you’re building a web app, mobile app, or microservice architecture, chances are you’ll need t…  ( 9 min )

It is the 19th. of May 2025 and I am behind on my blogging schedule, I am actually behind on a lot of schedules. But let's see if I can catch up a bit. Yesterday I sat down to do a maintenance release of Ebirah 0.12.0, when looking at the repository I noticed that I had not tagged and released: 0.11.0, so with that out of the way I started to look at: 0.12.0. The primary focus was the update of the base image from Perl 5.40.1 to Perl 5.40.2. I had recently updated my Docker tooling, but without noticing any changes until now. My editor VSCode suggested that I pinned the Docker image to a specific version , a technique I have used and am using with GitHub Actions. I thought this would be straight forward, but it turned out to be a bit more complicated than I expected. Not that it was compli…  ( 5 min )

Web applications come in many different forms and use various rendering patterns to display content to the user. These patterns dictate how the application is built, how it is served to users, and how it interacts with the browser. In this blog post, we will explore some of the most common rendering patterns used in web development, including static websites, single-page applications, server-side rendering (SSR), static site generation (SSG), incremental static regeneration (ISR), hydration, partial hydration, islands, streaming SSR, and resumability. Static websites are the most basic type of web application. They consist of HTML, CSS, and JavaScript files that are pre-rendered and served directly to the user's browser. This means that every page on the website is a separate file, and eac…  ( 6 min )

Starting my cloud computing journey with AWS Cloud Practitioner, I honestly struggled to grasp some of the concepts. Networking, IPs, even the general cloud terms, all felt new and overwhelming. Despite the struggles, I had already set a purpose: to understand why things work the way they do, not just memorize terms. So I started digging deeper apart from the AWS student guide, I watched YouTube explainers, reading more AWS docs, and learning from how experts on LinkedIn approach problems. One thing that helped a lot was reading how cloud professionals think about business needs of their clients, and how they approach AWS tools and services to solve them efficiently. Learning by Research & Reasoning CIDR and IP ranges Subnets and routing Internet Gateways and NAT Gateways I watched experts like NetworkChuck on youtube explaining how these connect in real cloud architectures, and attended a few expert sessions(like the ones from ALX) to build deeper understanding. I also documented everything on Notion, using toggles to organize concepts clearly and link them to real examples. Writing things out helped me make sense of abstract topics. Hands-On: Bringing It All Together After building that foundational understanding, I went hands-on with the AWS Console and practiced: Launching EC2 instances (choosing AMIs, instance types, configuring VPCs/subnets) Setting up IAM roles and using User Data scripts for automation Using key pairs and Git Bash to SSH into my instance Ran this command to verify the system: Got this output: 5.10.236-227.928.amzn2.x86_64 Amazon Linux 2 I explored basic Linux commands, storage configs, and how tagging and security groups improve structure and access. Progress Over Perfection I’m Curious… If you’ve walked the AWS learning path, what was your turning point? Was there a concept that “clicked” and made the rest easier? I Would love to hear how you approached your learning as a beginner or mentor. 👇  ( 4 min )

If this is a feature you want your application to have, and you happen to be using a different stack, you can still re…  ( 8 min )

TL;DR If you finished the Intro to ML post and thought, “Cool, but real data is way uglier,” this follow‑up is for you. We’ll use the same California Housing dataset so you can reuse your environment and immediately see the effects of each technique. When sensors drop packets or humans skip survey fields, you get NaN (Not‑a‑Number) entries. Most scikit‑learn models will straight‑up error if you feed them NaNs, so we MUST decide what to do. The three classic moves are: Strategy What it does When it’s OK Drop Columns Delete any column containing any NaNs Column is mostly NaNs or not predictive Imputation Replace NaNs with a statistic (mean/median) Numeric columns with moderate sparsity Extended Imputation Impute and add a boolean “was_missing” flag When the fact a value is missin…  ( 6 min )

The real problem with Web Components is simple: There is no clearly defined road to success for using them. No singular go-to guide. Up until recently the standard has been in flux. And in some ways, still is. But the core APIs have stabilized, and many developers are jumping into the scene. However, it can be hard for someone who hasn't followed the evolution of this standard to know where to begin. Learning the concepts necessary to use this powerful set of tools is a challenge.

AI-powered code suggestions from tools like Cursor and Windsurf can introduce security flaws for several reasons. First, these models are built on extensive datasets that include publicly available code and third-party libraries, many of which already contain known weaknesses. As a result, the AI may inadvertently learn and replicate those insecure patterns. Additionally, these tools often produce predictable and repetitive code structures that, while syntactically correct, may be vulnerable to exploitation if not verified properly. Another key concern is their limited understanding of the broader application environment, including specific business logic or security policies, leading to code suggestions that may function correctly but pose risks when deployed.

If you’ve worked with Laravel, you’ve typed php artisan serve php artisan migrate. And while those are useful, they barely scratch the surface of what Artisan can do. Artisan isn’t just a tool for running migrations or spinning up servers—it’s a command-line companion that can boost your productivity, simplify debugging, and teach you more about Laravel’s inner workings. Yet many developers (my past self included) tend to stick with the same 3-4 commands and miss out on some seriously powerful features. Whether you’re just starting with Laravel or you’ve been building apps for years, it’s worth revisiting Artisan with fresh eyes.

A class in JavaScript is a blueprint for creating objects. It allows you to define reusable object structures with properties and methods, making object creation and management more structured and efficient. JavaScript classes are a blueprint for creating objects. They introduce object-oriented programming (OOP) concepts like encapsulation, inheritance, and abstraction. Before ES6, JavaScript used constructor functions and prototypes to create and manage objects. With ES6, class syntax was introduced to provide a cleaner, more intuitive way to define object templates. JavaScript allows creating objects without classes using object literals, but classes provide advantages in scalability, maintainability, and reusability.

Hello friends 👋 In this blog, I will explain two simple and powerful tools in JavaScript: the AND (&&) and OR (||) operators. These are called logical operators and are used to check conditions. Let’s understand them with examples that relate to real life 🚶‍♂️🍕💻 AND (&&)? The && operator checks if both conditions are true ✅✅ If both are true → result is true If any one is false → result is false ❌ Let’s say you want to go for a walk 🚶‍♀️ You will go only if: ➡️ It is not raining ☀️ AND ➡️ You have free time 🕒 let isNotRaining = true; let hasFreeTime = true; if (isNotRaining && hasFreeTime) { console.log("You can go for a walk! 🚶‍♂️"); } else { console.log("Stay at home! 🏡"); } 📌 If both conditions are true, the walk will happen 📌 If even one is false, no walk today! OR (||)? The || operator checks if at least one condition is true ✅ If one is true → result is true If both are false → result is false ❌❌ You will order food 🍔 if: ➡️ You are hungry 😋 OR ➡️ There is no food at home 🍳 let isHungry = false; let noFoodAtHome = true; if (isHungry || noFoodAtHome) { console.log("Order food online! 🛵"); } else { console.log("No need to order food. Eat at home! 🍽️"); } 📌 Only one condition needs to be true to order food ➡️ && → Both conditions must be true ✅ AND ✅ ➡️ || → Only one condition needs to be true ✅ OR ❌ let hasLaptop = true; let hasInternet = false; // Check if you can work from home if (hasLaptop && hasInternet) { console.log("You can work from home 💻🏠"); } else { console.log("You can't work from home 😕"); } // Check if you can still do something useful if (hasLaptop || hasInternet) { console.log("You can still be productive! 💡"); } Operator Result is true if... AND Both conditions are true ✅✅ OR At least one condition is true ✅ or ✅ I hope this blog helps you understand AND and OR operators in a fun and easy way! 😊 These are very helpful when writing conditions in JavaScript.

Backend development architecture refers to the structural design and organization of the server-side components of a software application. It focuses on how the backend handles data processing, business logic, database interactions, authentication, API integrations, and server management to ensure scalability, security, and high performance. Modern backend architecture often leverages microservices, cloud-native infrastructure, containerization (like Docker and Kubernetes), RESTful and GraphQL APIs, and event-driven systems. Key trending concepts include serverless computing, API-first design, database optimization with NoSQL or NewSQL, and real-time data processing. This architecture plays a crucial role in building robust, maintainable, and scalable web and mobile applications that can handle complex user demands and evolving digital ecosystems.  ( 3 min )

Gamification can be a really powerful feature of any educational platform. When done right, it’s proven by platforms like Duolingo and Khan Academy to consistently engage students and boost retention. The trouble is that a lot of the features that these platforms have made famous like achievements, streaks and progress report emails can take weeks to build. This is why we built Trophy, to help developers build these gamification features much faster. To demonstrate this I built an example web application that hypothetical students could use to practice flashcards. Feel free to use this example app to start a new ed-tech project, or just as inspiration. This post has all the important snippets but for a full step-by-step walkthrough of how I built this app, check out the official tutorial, …  ( 8 min )

When Curiosity Strikes It always starts cute. You’re scrolling through LinkedIn, hear “AI is the future,” and suddenly your inner coder whispers: “Yeah, I’ll become an AI Engineer.” You open a YouTube tutorial, start learning Python, maybe dabble in a little scikit-learn... and for a moment, you feel invincible. Then Reality Hits Boom — you meet: Gradient Descent (why does it feel like I'm the one descending?) Backpropagation (stabbed in the back... with math) “CUDA not detected” (even though your GPU is flexing in Task Manager) Transformers (not the Optimus Prime kind ) Your innocent coding dreams become haunted by tensors and traceback errors. The Dev Setup, but Make it Chaotic You build your workstation: Dual monitors Fancy keyboard RGB lights Motivation? Fading... Mentally? Still in a baby playpen. Crying quietly as your LSTM forgets what it just learned. And Now You’re... Aged by 10 Years You started at 20. You debugged PyTorch for 3 nights. You now look like a retired philosopher sipping black coffee at 3AM. “I just wanted to make a chatbot…” But Here's the Truth... Every bug, every crash, every late-night meme scroll — it means you’re growing. So laugh at the chaos. Embrace the madness. Post the memes. Share the learnings. And keep going. Final Words To anyone out there struggling with AI engineering: You're not failing. You're just leveling up. Keep the curiosity alive. Keep coding. And never stop memeing your journey.

This post dives into Plang, an intent-based programming language that interprets natural language. For more, visit plang.is or get started here. Security is hard. As developers, we’re not exactly great at it. The issue is that security is binary - it either works 100% or it doesn’t at all. If there’s a flaw in your code, an attacker could gain full access to your system. Worse, you can never truly prove that something is 100% secure. All you can do is try to prevent every possible way in, which requires a lot of experience and a lot of eyes on the code. The only thing that gets you closer to 100% is time and scrutiny. That’s the key to secure code: experienced developers looking at it, lots of them, and enough time passing without a breach. We never know it’s secure. We can only hope. If I…  ( 5 min )

Hi, I'm Choice 👋🏽 I’m a Ruby on Rails developer with a background in chemistry — but really, I’m someone who’s rebuilding life from the inside out. My journey into tech wasn't linear. Like many Nigerians, I studied something safe (Chemistry), even though I’d always loved computers. Life happened, and I took detours that forced me to pause, reflect, and reimagine everything. Coding became more than a skill; it became a language of healing, structure, and hope. Since transitioning, I’ve built full-stack apps like ShopMe (e-commerce), DevConnect (developer community), and I’m currently working on TextMe, a real-time chat app. I’ve used tools like: Ruby on Rails (8), SolidQueue for background jobs AWS S3 for image storage React, Firebase, TailwindCSS, Bootstrap I’m also learning Django and Next.js 🌱 But beyond the tech, I’m creating soulful, user-centered projects — the kind that feel like quiet spaces on the internet. My content brand DearChoice is where I share faith, healing, and growth. My passion project Yardly aims to help communities in Nigeria discover local talents and preserve culture — online. I want to connect with devs who are learning with heart. Who are figuring things out slowly. Who care about the why, not just the how. If that sounds like you, let’s chat 🤝 Let’s build, share, reflect — and grow better together. ✨ 🧩 You can check out my projects on GitHub @ChoiceG 💼 And find me on LinkedIn See you around! – Choice 🌿  ( 3 min )

If you've ever pushed a hotfix on Friday, only to get a bug report five minutes later… You know the pain of mobile testing. Between flaky UI tests, emulator delays, and device-specific weirdness, testing often feels like guesswork. We wanted something cleaner and found that API-driven mobile testing changes the game. Emulators that crash at the worst times Tests that pass locally but fail in CI Writing brittle UI test scripts that break on every UI tweak Hours wasted waiting for device builds to finish Sound familiar? We figured there had to be a better way - and there is. Instead of relying solely on UI flows, we started triggering mobile app behavior via APIs during CI runs. This gave us: More control over test execution The ability to skip the UI when not needed True automation across devices, even without a UI Turns out, you don’t need to “see” the app to know it’s working - you just need to test the right paths, fast. We integrated a lightweight API testing layer into our existing pipeline. We used a tool that let us: Run tests on real devices, remotely Trigger workflows from GitHub Actions Receive results via webhook Skip maintaining emulator scripts It plugged into our pipeline almost effortlessly, and we never looked back. Less flakiness Faster feedback Works across device types Easy to scale Most importantly, it lets us move fast without breaking things. We tried a few things, but ended up using tools like NativeBridge(the cheapest), Appetize, BrowserStack, and Lambda that made the API integration part smooth. No SDK installs, no heavy setup — just clean test runs triggered by API. We didn’t plan to switch our whole testing strategy, but it kind of happened naturally once we saw how stable and scalable it felt. You don’t need to rewrite your entire testing suite. Just look for places where API-driven checks can replace manual ones — and start small. It’s not about being trendy — it’s about not burning out your dev team maintaining flaky test code.  ( 4 min )

Today, I learned about CSS Transforms, and I’m excited to share what I discovered! The transform property in CSS lets you visually manipulate elements — you can move, rotate, scale, and skew them without changing the actual layout. It's super useful for animations, hover effects, and modern UI design. Here are some common 2D transform functions: translate(x, y) Moves an element from its original position. transform: translate(50px, 100px); rotate(angle) Rotates an element clockwise. transform: rotate(45deg); scale(x, y) Scales an element in the X and Y directions. transform: scale(1.5, 1.5); skew(x-angle, y-angle) Skews the element. transform: skew(20deg, 10deg); 3D transforms add depth to your elements and make them appear to move in 3D space. To view them properly, you often need to use the perspective property on the parent container. rotateX(angle) Rotates the element around the X-axis. transform: rotateX(45deg); rotateY(angle) Rotates the element around the Y-axis. transform: rotateY(45deg); rotateZ(angle) Rotates the element around the Z-axis (similar to 2D rotate). transform: rotateZ(45deg); translateZ(distance) Moves the element closer or farther away in 3D space. transform: translateZ(50px); perspective(n) Defines the distance between the viewer and the 3D element. .parent { perspective: 500px; } .box { width: 100px; height: 100px; background: teal; transition: transform 0.3s; } .box:hover { transform: scale(1.2) rotate(10deg); } When you hover over the box, it grows and rotates — all thanks to the transform property! CSS transforms (2D and 3D) are powerful tools that add creativity and interaction to your web designs. I enjoyed experimenting with different effects and seeing how elements can move and rotate on screen. Next, I’m planning to learn about CSS animations and how they work with transforms.  ( 4 min )

Hello everyone 👋 I’ve recently started building a personal open source project called Cartouche. It’s a one-user social network simulator. You write posts like on Twitter, and get reactions from hundreds (or thousands) of AI bots — each with memory, personality, and their own behavior. The idea Cartouche is a place to express yourself freely — without the pressure of real audiences. You get thoughtful replies, memes, debates, praise, skepticism, and support… but all of it from simulated users with their own quirks and styles. They react over time, not instantly. Some follow you, others unfollow. Some remember what you said weeks ago. Some adore you. Some argue. Some just drop a meme and vanish. It’s a space for testing ideas, exploring identity, or just yelling into a virtual crowd that somehow yells back — in meaningful, sometimes surprising ways. Why? Because sometimes you want feedback — but not from real people. What's built so far? A small piece of the frontend (React + Vite) A mobile-first UI (with live demo): View Demo Figma design (mobile): View on Figma GitHub repo: Cartouche on GitHub Full project overview (Gist): Read here Tech stack (planned) Frontend: React + Vite (hosted via Nginx in Docker) Backend: Python (likely FastAPI) Storage: MinIO for media Database: MySQL, maybe Redis AI: Google Gemini API (or user’s choice) Deployment: All via Docker Compose, one-command setup Looking for like-minded folks I’m building this solo for now. It’s a pet project — no deadlines, no pressure, no money involved. Just a place to build something interesting and fun. If this concept resonates with you and you'd like to contribute — whether with code, ideas, or questions — feel free to reach out. Happy to chat. Thanks for reading. — @metimol  ( 3 min )

Have you ever thought about how the simple act of weaving cloth is connected to the computers we use today? It might sound surprising, but the story of computers begins with weaving looms! Long ago, people used looms to weave fabric. These looms created patterns by controlling how threads crossed each other. In the early 1800s, a clever inventor named Joseph-Marie Jacquard invented a loom that used punched cards to tell the machine which pattern to weave. These cards acted like instructions — telling the loom what to do step by step. This was one of the first examples of a programmable machine — a machine that could follow a set of instructions automatically. Around the same time, inventors were building machines to help with calculations. People like Blaise Pascal and Gottfried Wilhelm Le…  ( 4 min )

Modern web applications aren’t just a collection of components and APIs anymore. They are dynamic, performance-sensitive ecosystems that need to scale across teams, features, and platforms. And that’s exactly where frontend architecture comes into play. In this post, we'll unpack what it takes to architect scalable frontend systems that stand the test of team growth, feature sprawl, and user expectations. Scalability in frontend engineering is about building systems that: Support fast and parallel feature development Withstand large codebases and contributor counts Offer consistent, maintainable patterns Perform well under heavy user load It requires a blend of technical chops, UX thinking, and DevOps maturity. It's not just about writing good code—it's about enabling others to do the same…  ( 5 min )

A Tale of Probot, Lambda, and a Bot Called Rupert 🤖 Meet Sam, our fictional senior developer. You may remember them from their first adventure exploring AWS S3 storage classes ☁️ or their reluctant encounter with AWS Cognito 🔐. Sam had just closed their fifth GitHub issue of the morning, all of them some variation of “Thanks for reporting!” or “We’ll look into it soon 🫣.” Copy, paste, rephrase, repeat — across three different repositories. It was the kind of thing that made them question their life choices — and wonder if they should’ve just opened that dog daycare center instead. Somewhere in the middle of googling “automate GitHub issue responses without losing your soul” 😩, they found it: Probot. A framework for building GitHub Apps. It lets you hook into GitHub events — like issu…  ( 9 min )

There's a term out there in the AI community today that everybody's using: Multimodal RAG. Let's get this "RAG" out of the way before we dive into Multimodal RAG. RAG stands for Retrieval-Augmented Generation. Think of it like this: "Go find some helpful info, mix it with what you know, and then give me a smart answer." Here's the deal - you know those AI chatbots like ChatGPT that seem super smart? Well, they've learned tons of stuff, but they have some problems. Sometimes their knowledge is outdated, or when you ask about something really specific, they just shrug and say "Sorry, no idea." That's where RAG comes to the rescue. Before the AI answers you, it acts like a detective. It searches through fresh databases, company documents, maybe even the internet, to find the most up-to-date …  ( 8 min )

Castle Dynamic Proxy: github Castle Dynamic Proxy is a powerful library for generating dynamic proxy objects at runtime in .NET. It is widely used in mocking frameworks like Moq to simulate and intercept the behavior of objects during testing. In mocking scenarios, Dynamic Proxy allows developers to create fake implementations of interfaces or virtual methods. These proxy objects can: By enabling such features, Castle Dynamic Proxy plays a key role in unit testing, dependency isolation and aspect-oriented programming(AOP) in the .NET ecosystem. What's a proxy? What is an interception pipeline? A simple example for Dynamic Proxy: Note: If you implement an interceptor and handle the method, the method is handled. If you don't handle it, nothing happens and it may return null. public interfac…  ( 4 min )

In FastAPI, how route handlers (endpoints) behave in terms of parallelism and concurrency depends on whether they are defined using async def or def, and whether the work inside them is I/O-bound or CPU-bound. Here are the four combinations of route handlers and how they affect parallel or concurrent handling of requests: async def with async I/O-bound work (e.g., await asyncio.sleep, database calls) @router.get("/async-io") async def async_io_route(): await asyncio.sleep(2) return {"status": "async io"} Handled concurrently Non-blocking — multiple such requests can be handled at the same time. Best performance for I/O tasks like DB queries, network calls, file access. async def with CPU-bound work (e.g., heavy computation, no await) @router.get("/async-cpu") async def …  ( 4 min )

We are continuing the blog series about testing your AWS alarms. The first part of the series, which looked at CloudWatch actions and EC2 alarms, can be found here. An untested alarm is not one you can trust. This time we will look at alarms for your Lambda functions. As before, we will test the alarms by ”breaking” the Lambda so you get the same outcome as when a real issue would occur. Since this is Lambda, we will add code (or entire Lambdas) to make the Lambda act as we want. I will use Python, but the logic works for all the other supported languages. I have an examples repo where you can find Terraform code to deploy Lambas and required resources to AWS to test the alarms. You will need to connect your alarms to the Lambda functions, though. Remember to lower the thresholds on your a…  ( 6 min )

A growing problem with my home lab is password fatigue. Each time I add a new service to my network, I generate a new random password for it. I got by initially with using a different password for every service by storing them in a password manager, but as the number of services exceeded double digits, having to open my password manager every time I want to access each service is starting to hinder my productivity. I needed a self-hosted SSO solution for my home lab services, so I deployed an open-source IAM platform that supports SSO via OIDC, OAuth, and LDAP protocols to my Kubernetes cluster. The initial design was simple. I only needed SSO for my services, namely Grafana and Syncthing, and my solution must support both modern protocols like OAuth/OIDC and legacy protocols like LDAP.

Originally published at https://www.nocobase.com/en/blog/open-source-ticketing-systems. Last year, as the number of NocoBase users grew, we faced a pressing challenge: how to efficiently manage customer feedback and support requests. Users reached out via emails, community forums, and even through internal colleagues. With information scattered across multiple channels, issues were easily missed, and collaboration on follow-ups became cumbersome. We realized it was time to implement a ticketing system tailored to our workflows. So, we decided to build our own custom ticketing system using NocoBase. During this process, we tested several open-source projects and identified some excellent tools, while also defining the core features essential for an effective ticketing system.

Schemas in PostgreSQL aren’t just for large systems—they’re for anyone who wants to keep their data structured. A schema is like a folder within your database where related objects (tables, views, etc.) are grouped together. This helps you separate concerns, organize logic, and secure your data more effectively. Here’s a practical look at how they work. Organization: Separate business domains (like inventory and users). Control: Limit access to different parts of your app. Maintenance: Make backups and updates more targeted. Cleaner Queries: Avoid clutter in your namespace. Comes with every PostgreSQL database. If you don’t specify a schema, objects go here. Created manually to isolate logic or control access. CREATE SCHEMA hr; How Data is Structured PostgreSQL Cluster └── Database └── Schema └── Tables, Views, Functions, etc. This layered model helps manage growing projects without chaos. CREATE SCHEMA inventory; CREATE TABLE inventory.products ( product_id serial PRIMARY KEY, product_name VARCHAR(255), price DECIMAL, stock_quantity INT ); CREATE TABLE public.users ( user_id serial PRIMARY KEY, username TEXT, email TEXT ); Using schemas lets you organize your app by responsibility—making it easier to evolve or scale parts of your system. Yes, and it’s a common best practice. Public is open by default; custom is restricted unless granted. Not directly, but they help manage large systems more cleanly. Yes, using tools like pg_dump or schema migration scripts. PostgreSQL schemas give you better structure, access control, and scalability. They're an essential tool for organizing your data without complicating your architecture. For a more detailed guide, visit the schemas in PostgreSQL article.  ( 17 min )

Docker has revolutionized the way developers build, ship, and run applications. Whether you're a beginner or an experienced developer, mastering these essential Docker commands and tips will make you more efficient and productive. Before using Docker, ensure you have it installed by running: docker --version To get detailed system info, use: docker info Quickly run a container with: docker run -d -p 8080:80 --name my-container nginx This runs an Nginx server in detached mode (-d), mapping port 8080 on your machine to port 80 inside the container. To see all running containers: docker ps To include stopped containers: docker ps -a Stop a running container: docker stop my-container Remove a stopped container: docker rm my-container Remove all stopped containers at once: docker rm $(docker ps -aq) Over time, unused images take up space. Remove them with: docker image prune -a If you have a Dockerfile, build an image with: docker build -t my-app . This tags the image as my-app. Use interactive mode to execute commands inside a running container: docker exec -it my-container /bin/sh For Ubuntu-based containers, use /bin/bash. Monitor logs with: docker logs -f my-container The -f flag shows real-time updates. Copy files from your local machine to a running container: docker cp myfile.txt my-container:/app/ Copy files from a container to your machine: docker cp my-container:/app/myfile.txt . Instead of running multiple containers manually, define them in docker-compose.yml and start them with: docker-compose up -d Stop and remove all services: docker-compose down 💼 LinkedIn | 📂 GitHub | ✍️ Dev.to | 🌐 Hashnode Found this useful?

This feels so fluid… how do they do that?’" If you're a frontend developer in 2025, chances are you’ve asked yourself this at least once. Animations have quietly become one of the most influential parts of the user experience. They’re no longer just about making things "look cool"—they guide the user, provide feedback, and elevate interaction into engagement. In the early 2010s, animations were mostly afterthoughts—extra polish added at the end of a project if there was time. Today, they are baked into the design process from Day 1. With products competing for attention in milliseconds, smooth transitions, responsive feedback, and motion-based storytelling are the new UX fundamentals. But here's the catch—not a…  ( 8 min )

SQL gives us the handy SELECT * to quickly grab all columns from a table but should we really use it in production? Some developers love the speed and convenience of SELECT *, especially during prototyping or when working with wide tables. Others argue it leads to performance issues, tight coupling, and unreadable queries and insist on selecting only the columns you actually need.
